Horizontal mesh nixies

[Alic]

The nixies with horizontal mesh are quite popular. I like them a lot!
First I thought that there was only the CD66, but then I discovered the ZM1210, ZM1177 and CD64.
But there must be more. Which nixies am I missing?

[Paul Andrews]

Mullard seemed to specialize in them. This page shows several: http://www.webx.dk/oz2cpu/clock/nixie-collection (hopefully I typed that right - I'm on my phone).

The link is correct, but the .htm was missing ;-)
Here's the working link :
http://www.webx.dk/oz2cpu/clock/nixie-collection.htm

You're right, there seem to be quite a few Mullard nixies like this :
ZM1075 (no dot)
ZM1175 (left dot)
ZM1172 (no dot)

Always nice to see nice pictures of nixies!
Thanks a lot!

There is also a special version of the IN-16

[Paul Andrews]

And the ZM1212.

And a pair of inverted nixies, ZM1230 and ZM1232

[Alic]

Thanks!
I have the special IN-16, but I never looked close enough to notice that it really is a horizontal mesh nixie!
The inverted types are very nice! I'll have to check the English eBay more often.

CD66A seems to come with both rectangular and horizontal meshes. I just received 6 used CD66A (bad condition, only one has the marking partially readable, some have remains of red filter, 2 out of 6 are dead) and I'm googling for more information on those and many photos show back of tube with CD66A and front with rectangular mesh.

JB shows the rectangular mesh version and mentions it is identical to ZM1242

Datasheet from Dieters page shows a CD66(A) with horizontal mesh. 

Looking at more pages you can get even more confused. It really seems like few different productions from NEC were labelled as CD66 or CD66A.

Anyone know if there are any negative performance issues to a horizontal
mesh, or as in the case of Burroughs b7032 which has no mesh at all?

In the case of no mesh you do get more sputtering, that is, darkened
glass. In case of a mesh you get a "sputtering shadow" as can be seen on
the Wikipedia image [

I have a set of Mullard ZM1232s that show the mesh off really well.

These will be going into an antipodean styled clock

[Tomasz Kowalczyk]

Do you mean a regular clock made with upside down tubes? I was planning something like this with B-5445s, with a small label on the front with something like "The Australian Clock" written on it - of course, also upside down. 

[Roddy Scott]

G'day, Cobber!

Unfortunately, Tomasz, none of my clocks seem to be regular! I have a very specific design in mind for them but the wood work is a bit on the complicated side to do but somehow I will find a way to get what I am thinking into reality so, as they say, watch this space!

[Roddy Scott]

Ooops! Wrong Photo! That's a ZM1175!

[Tomasz Kowalczyk]

I see the upside down 7, so it probably is the right photo. A really good looking tube! 

[Roddy Scott]

I must be getting senile! 

You are right, it is a ZM1232.

I was a discussion with another member where I sent him the wrong photo and thought I put the same in here.
