A blunderbuss with an early lock

[Pukka Bundook]

Iskender,

I don't want to belabour the issue, but a normal dog -catch can't just be pulled back at half cock, and when the lock is full cocked, the action of cocking automatically slides the dog catch back over, out of the way.

I think this is a very neat feature and something of a minor mechanical delight!

Best wishes, Richard.
