Well Chris and David: Thanks for the enlightenment on the brass shell casing. This was definitely what Chris was looking for. I tried very hard to get the seller to send it to me via other means, in order to forward it on. But to no avail. DUUUUH! It's now gone.
There's a couple more units on market place I'll see if I can put you in touch with. Just not sure if they're 4.5 inch.
And as for the idiot who sold the other one, an old English friend from many many years ago would refer to him "as useless as tits on a frog's ass". Pass this around boys!
We'll keep looking......R
