I am about to scratch built M20 RR. As the only available one is resin, and costs as a annual budget of third world country, i'll give my best at producing this item.
Is there anyone that could help me with either:
1) real 1:1 dimensions
2) dimensions of DML 1:16 kit
3) dimensions of resin 1:35 kit?

I found out that the barrel length was 2080mm. How thick was it? 75mm should be 2,14mm in 1:35, but that is the inner diameter. How "fat"would the barrel be - 2,5mm, 3mm perhaps?

How long was the visible part of the barrel? I found the data on 1700mm in reality,but is that true?

What was the length of conic part,and what would be the length and the thickness of the back-end part?

Thanks in advance,
Marko Milosevic

Maybe you would get more answers if you posted this question in the Armor/AFV-forum ?
