PPSh-41: Barrel assembly

I finally found a tube the right size for the barrel. Surprisingly, the barrel for this gun is only 10.5 inches! Once I had the right tube, I could finally drill a hole through the breach block

The dummy bullet that I made fits snugly in the breach.

and the barrel fits beautifully within the shroud. It is not glued, but held in place by a screw post.
