Kent,
The main reason for me deciding to make new cock is to avoid messing with the original. The input I got is excellent, however an repair, no matter how well done, is a permanent irevocable change. I did have to repair some cracks in the forearm that I suspect were caused by stock shrinkage.
I think the main reason I will make a replacement is because the cock is easy to take off and put back on. I will probably make the whole assembly and keep the entire original assembly intact. A new cock will allow the lock to function properly with out being further damaged.
I would like to shoot this rifle, as it should give me a good idea of the accuracy of this class of rifle. It has an interesting bore configuration in the the muzzle is smooth bored for 3.75 inches before the rifling starts.
The C/YC is the marking for the Cobham Yeomanry Cavalry, which was a volunteer cavalry unit raised in the 1790s by the Earl of Darnley. The Earl bought rifled carbines from Nock in 1799. This particular rifle was sold off when the Earl of Darnley sold Cobam Hall in 1957. There are 4 of these carbines I have come across evidence of. The gun is very similar to the 1796 Heavy Dragoon carbine that Nock designed and are very similar to the original configuration of the screwless lock rifled carbine version that the London & Westminster Light Horse Volunteers contracted from him for their rifle unit.
