Just in, a as new cased Drulov repeater. Kind of fascinated me for a while given I read it used a similar idea started by Benjamin with their repeater: but done successfully. I had a Crosman 600 for a bit it’s got a lot going on and is a bit of a gas hog. This held gas and works perfectly with its first shoots. Multiple sets of seals came in the case. Only mystery was the solid cone shaped piece. Have no idea what it is for? Any thoughts?
