Thanks Dennis.Yes, I'd love to buy a set of plans,but "only$50" translates to quite a bit of money for me (I live in South Africa) to build what is basically a toy - ok, a very detailed toy ;-)

Thanks for the dimensions. It makes sense. (2.374" x3) is what the diameter of the breech casing (?) seems to be compared to a man's head on one of the photos I have.

I really appreciate your help.
I might be back for more if that's ok by you.

Once again,thank you very much.

Cheers
Richard
