I dug this out today to work on between other projects.
It's a resin kit missing the barrel and a metal barrel had no body.
I'll need to source a metal or plastic tube to mount the barrel to the body.
The resin parts are kind rough, it's a true "garage" kit
The metal parts were professionally turned and a very high quality.
So far all I have done is sort the parts and figure out whats getting used and done some sanding and filling of pin holes. There are lots of them!
This will be a long term project
