Looking through the entire DSOs file on microfilm, we seem to be able to create four pattern-based groups when it comes to how cars and radios were ordered:
Group A: DSOs 2501-2523 (the ‘early’ cars), ordered by ‘G.W. Nuznoff’ (‘received’ August & September 1966) did itemize an AM radio on every DSO except 2513 and 2514, both of which ended up getting cancelled.
Group B: When Dr. Ray A. Geddes took over ordering (i.e. his name started appearing on the orders), DSOs 2524-2540 (‘received’ in October 1966) all originally had “AM Radio” typed in the options box, however, each was then scribbled out by hand on every DSOs in this range. Perhaps a cost-cutting after-thought?
Note: There is one exception found in Group B, and we believe this exception is most-likely due to a human error during data entry to the Ford computer system. DSO 2532 was for 70x G.T. 500 Automatic cars (410F package). The cars on this DSO did receive AM radios (per the sampling of Marti reports collected on cars attached to this DSO), however, no Change Notice was found in the microfilm file. This one exception/mistake resulted in 70 cars getting radios that probably shouldn’t have. [Hopefully we can obtain some SAI Production Orders for cars ordered by DSO 2532 to see how they’re marked]. The Marti reports & invoices (collected so far) that support this single DSO exception include cars: #0314, #0320, #0359, #0363.
Group C: DSOs 2541-2578 (‘received’ in November and December 1966) had no obvious pattern as to which units were ordered with a radio and which ones were not. Note: DSO 2541 is also when item number ranges started to appear on the orders:
DSOs with AM radio: 2542, 2545, 2547, 2548, 2550, 2552, 2553, 2554, 2556, 2558, 2561, 2563, 2564, 2565, 2567, 2569, 2570.
DSOs without AM radio: 2541, 2543, 2544, 2546, 2549, 2551, 2555, 2557, 2559, 2560, 2562, 2566, 2568, 2571- 2584.
Group D: DSOs 2285-2614 (‘received’ in February and March 1967 - the last two months of orders) all followed a precise pattern that included AM radios with all Air Conditioning equipped cars (“Selectaire”). Simply stated: if the car wasn't ordered with air-conditioning, it wasn’t ordered with a radio.
DSOs with AM radio (All have AC): 2585, 2587, 2593, 2595, 2597, 2599, 2600, 2602, 2605, 2607, 2611, 2613.
DSOs without radio (not AC): 2586, 2588-92, 2594, 2596, 2598, 2601, 2603, 2604, 2606, 2608, 2609, 2610, 2612, 2614
Comparing the DSO Microfilm to the Ford record:
DSOs (and SVOs) are “pre-production.” The Ford Record (Marti) is supposed to be “post-production,” and is therefore usually the most accurate information we can use. In research, when these two data sources match, we know we have accurate information!
DSOs on microfilm (and Marti reports) gave us the following totals:
Radio-equipped cars: 462 (461) approx 14% of total
Non-radio cars: 2672 (2672) approx 86% of total
Note: A Marti report provided a total of 461 radio-equipped cars. Marti reports production quantities have been known to be off by a unit or two on occasion, often depending on the year the report was printed. Kevin's numbers (461+2672) only add up to 3,223 units, which is short of the 3,225 known serialized G.T. units. It's possible that #0176, #0131 and/or #0139 may be the discrepancies in the totals.
DSOs account for 3,224 cars in total. This differs from the registry’s total of 3,225. The registry counts car #0176 because it has a Shelby sequence number, however, Marti reports typically have not counted this car because it was not ordered by Shelby American (we assume Marti’s query is simply if [dealer]=X999).
