I picked these up in the hopes to make shooters out of them. The one with most of the parts is locked up tight! I've been messing with them the last couple evenings.

I soaked the receiver with the lever overnight in Evapo-rust. It managed to get rid of most of the rust. Plus the parts started to loosen up. I can see how great they look already. Man these are going to be fun little guns!
On the short list of parts that I need to get are barrels and some little springs. I have scrap metal to make my little bits out of and I have a huge plank of walnut tucked away in the rafters of my shop.
I have a few questions about these Crackshot's. Well, I guess for any owners of Crackshot's. I'd like to get a sketch of the barrel if possible. It is a pretty small diameter barrel. I think the bore might have to be offset to make room for the extractor. A sketch of the extractor would be nice also

I'm thinking that the lug to hold the barrel on will need to be dovetailed into the barrel then soldered on?
Thanks in advance,
