OMG!! Congratulations !! A very early, and very rare, English doglock musket. Where did you find it ?? And, as Richard says, very deserving of some good photos. In that regard........if you want some assistance in taking photos, you are welcome to send the gun to me
I'll even pay the shipping both ways
Seriously, it's a wonderful aquisition. These are so rarely seen, especially in such complete condition. Some early observations:
The stock profile, and the overall large proportions put this gun in the time frame you first mention above. Probably not any latter. Notice the trigger guard is simply screwed unto the stock, with no inletting to the stock. A common feature. I can't tell from the photos here, but it could have been made without an iron butt plate. Would not surprise me.
LOCK: English doglocks seemed to have appeared since at least the 1640's, in various styles. The early doglocks I've seen had three lock plate screws securing the lock to the stock. This lock appears to have only two, but with a third small screw securing the tail of the lock plate from the lock side. Interesting. But what I first noticed was the hammer stop mounted on the outside of the lock plate. This is a feature seen on snaphaunce locks, which pre-date the doglock. See photo below. Which may suggest that the lock pre-dates 1680 as a transition type of lock. Or it could be that the lock maker simply wanted to keep this feature. Or maybe the lock is even older than the rest of the gun. But from these photos, it looks like the gun was all made together.
Again, Congratulations. A great find. Please post additional photos when you have a chance. Hopefully showing the lock internals. Would be most anxious to see them.
