Roy Hebbes,
Sorry to be pedantic but its P Webley (not T), as in the famous Screw Grip.
Gunsaholic,
I have a E Woods in my stock list that incorporates the same patent.
When this gun came to me, the spring that operates the 'snap action' was broken and I had to make another which was quite a challenge.
In my gun, the spring is a V spring let in to the internal flat back of the breech. It works on a lever that operates on an 'over centre' principle: pushing the lever to fully open or fully closed but neutral in the middle of the lever movement.
Judging by the strength of the original spring it was intended to fully close the lever and as such was a major hazard to fingers positioned between trigger guard and lever on its closing movement.
The spring I replaced it with is a much lighter spring which doesn't threaten to amputate ill positioned fingers!
As another poster mentioned, guns of this age had no shot or chamber length marks: maximum load didn't come in to 1896 and chamber length wasn't mentioned until 1925.
Exception to this was the diamond mark for nominal chamber size which included a LC (as opposed to a simple C) when the chamber was longer that 2 3/4" and proofed for a heavy load. This is rarely seen and given its rarity, I suspect the criteria for this unusual mark are a bit obscure.
