Colt Serial Number Database

[Heron Mathis]

Pleasebe advised that the information provided here is approximate, and should not be relied upon for legal, compliance, valuation, or other purposes which require definitive documentation. Enter the serial number, without spaces or dashes, to search the database. If multiple models appear for your serial number simply match the date with the appropriate model, as certain vintage firearms can share serial numbers between different models. If your firearm does not appear in the listing, please understand that this is not a comprehensive database. If you wish to purchase a Letter of Authenticity with more definitive information for your firearm, please contact Colt Archive Properties, LLC.

The Diplometrics Program has built and released databases on international organizations, diplomatic exchange (embassies), and treaties monitored by the United Nations, including the Country & Organization Leader Travel Database (COLT). The Diplometrics Program has also developed tools to help visualize and structure the data, such as the UN Voting Coincidence Dashboard. This data feeds a research agenda that is interested in measuring and modeling international relations and will inform the International Politics submodule of the International Futures (IFs) model.

The project expects to add to this data collection effort by producing data sets on non-state actors including international non-governmental organizations, multinational corporations, and others.

Identifying the foreign travel of heads of government and state is a key component of understanding the policy interests of countries, geopolitical relationships, and international power dynamics. The COLT Database seeks to provide novel data measuring travel events for heads of government and state, as well as a number of select intergovernmental organization leaders and key ministers of select states.

The goal of the COLT project is to construct a database of foreign travel by Heads of Government and State (HOGS) for over 200 countries from 1990 through the present. Travel by foreign and defense ministers (sub-HOGS) is coded from 1990 to the present for the United States, Russia, and China, and from 2018 through the present for all foreign, defense, and finance minister-equivalents for all Group of 20 member countries.

The COLT Database collects information from a broad sample of source material, recording all HOGS international travel, while also providing information that can help users evaluate the nature and aims of these visits. The Database consists of three unique leader-centric datasets: travel, biographical information, and education. While COLT is currently a proprietary dataset, we hope to soon share these data publicly.

Package cern.colt.list DescriptionResizable lists holding objects or primitive data types such as int, double, etc. For non-resizable lists (1-dimensional matrices) see package cern.colt.matrix.

The list package offers flexible object oriented abstractions modelling dynamically resizing lists holding objects or primitive data types such as int, double, etc. It is designed to be scalable in terms of performance and memory requirements.

File-based I/O can be achieved through the standard Java built-in serialization mechanism. All classes implement the Serializable interface. However, the toolkit is entirely decoupled from advanced I/O. It provides data structures and algorithms only. This toolkit borrows concepts and terminology from the Javasoft Collections framework written by Josh Bloch and introduced in JDK 1.2. 2. IntroductionLists are fundamental to virtually any application. Large scale resizable lists are, for example, used in scientific computations, simulations database management systems, to name just a few.

A list is a container holding elements that can be accessed via zero-based indexes. Lists may be implemented in different ways (most commonly with arrays). A resizable list automatically grows as elements are added. The lists of this package do not automatically shrink. Shrinking needs to be triggered by explicitly calling trimToSize() methods.

Growing policy: A list implemented with arrays initially has a certain initialCapacity - per default 10 elements, but customizable upon instance construction. As elements are added, this capacity may nomore be sufficient. When a list is automatically grown, its capacity is expanded to 1.5*currentCapacity. Thus, excessive resizing (involving copying) is avoided.

Any list can be copied. A copy is equal to the original but entirely independent of the original. So changes in the copy are not reflected in the original, and vice-versa. 3. Organization of this packageClass naming follows the schema List. For example, we have a DoubleArrayList, which is a list holding double elements implemented with double[] arrays.

The classes for lists of a given value type are derived from a common abstract base class tagged AbstractList. For example, all lists operating on double elements are derived from AbstractDoubleList, which in turn is derived from an abstract base class tying together all lists regardless of value type, AbstractList, which finally is rooted in grandmother AbstractCollection. The abstract base classes provide skeleton implementations for all but few methods. Experimental data layouts (such as compressed, sparse, linked, etc.) can easily be implemented and inherit a rich set of functionality. Have a look at the javadoc tree view to get the broad picture.

I am getting ready to letter everything in my collection that can be lettered, including my Colts. As part of my prep work, I am inputting the serial number of all my Colts into their online serial number lookup thing. On a whim, I typed in the number from my Remington Rand 1911A1, and it came back saying made in 1944, which aligns to several other online lists of who made what during the War. On a further whim, I input a few random numbers from serial number ranges listed as assigned to other manufacturers, and then I even found pics online of non Colt 1911A1's made during the War and put them in. All of them came back with a date on the Colt Website. Granted, these were made under license, so I guess Colt would have records, but I was still surprised. I'll be curious to see what happens when I letter the gun.

Has anyone here got a WWII 1911 made by other than Colt, and have you tried to letter it? If so, what happened?

It seems that there is more to the Colt letter database than any of us realize.

I wonder what'll happen when I try to letter an 1860 that has been cartridge converted, apparently twice, and has 2 different serial numbers. The one on the butt is the same as the one on the frame, except that the one on the frame has an extra 8 on it in a different font and oddly spaced. I wonder if Colt added the 8 when they did the initial conversion? Both numbers come back as being an 1860. One made in 61, the other in 63.

Curiouser and curiouser.

i also have a 1943 ithical 1911A1 that ive confirmed where it was sent , ive not checked it on the colt site and would never have thought to do so , i know when it was mfgred and when it shipped and to whom , but i might have to look just for S&G to see what colts records say ,

I am trying to register my KWPN colt and need to submit DNA form for his dam who is TB. Form asks for registration #s for her, we sire, and her dam and of course I cannot find her papers anywhere.

[QUOTE=JoannaHCR;8966170]

I just called the Jockey Club for mine, they were a little hesitant to give registration numbers, but after I explained I was trying to get her approved for a WB registry, they gave them.
