Thanks Gents, that's where I thought I stood. I'll probably engineer something with modern parts, and shoot while I search.

Could I bother you to tell me a bit about the gun? I understand it to be "Greener type" is that correct? Was it a target gun with that big top rib? Is the bottom rib and creaning rod unusual, I see them on WR "improved" Martinis, but not Martinis? What do you estimate DOM to be?

Thanks

Mark
