Are you having a laugh?
If by that you mean, am I trying to play a trick on people, No. This vehicle existed, and I have seen pictorial evidence of it, on which I am basing my build. Apparently it is obscure.
So far Doc Twilight has been asking the best questions in that his questions potentially help everyone arrive at the answer. Many questions have simply been to ask if the build is a specific entity. These have to be asked, but in the twenty-questions game, I think these specific identity questions are premature. First we need some more questions along the lines of "Is it vegetable?", "Does it walk on four legs?", "Does it have a brain?", etc.
In that they narrow the focus considerably, these are the most revealing questions and answers so far:
Is that an armored car?
Yes
Is this an actual historical vehicle?
Yes
Is this a British vehicle?
No
Is it French?
No
Was this vehicle designed/built for use between the end of the Russian Civil War and 1945?
No
