I just snagged this:
I've got a scintillation probe. Now all I need to do is figure out how to hook it up. I already asked on the GeigerCounters group but no one has the manual.
Then there's this little toy:
Not powered up. Seller has zero feedback. Hmm...

It says it was a movie prop... I wonder what movie and how? Pretty wild.

They were suggesting it would make a good movie prop. I think my Dawe counter looks cooler:

It could also be a shorted Nixie, I had that recently, just whacking it gently with a pencil fixed that one but I’ve read about people burning off shorts inside Nixies with low voltag high current. Have you tested another Nixie in its position or swapped places on two of them to see if the fault follows the Nixie?
The DAWE one looks a lot like what AVO built (or whoever the original designer was, in many cases Marconi when it comes to some AVO designs), I’ll try to find my AVO manual and see if they are in any way similar.

Funny. I have had the same counter for 10 years or so.. with the difference that it is connected to the 3022B unit beneath it. I have never gotten around to powering it up... and there is too much heavy stuff in front of the shelf to get to the counters right now.. :) Somewhere I have the manual for bottom unit (3022B) .. I have nothing for the top one though.
And yes I love them; "Moonbase Alpha" gear :D

The top unit is supposedly named 3001a, check Radiomuseum and also a thread at the UKVRRR forum where dodgy driver transistors where mentioned as a common Nixie problem.

I hear that. Here's another model being used in the BBC Radiophonic Workshop:
Hint: it's under the scope. The EMS Synthi 100 came with it. Full history of the Radiophonic Workshop here:

I'd like to see that.

I guess I should drag out all the SF-looking stuff for a group shot.
