I know, I know could have been anyone under the sun in Wolverton, Birmingham or London. But there is always someone out there that might have an idea. It's from an 1888 James Lang sidelock. Very simple design, but the main spring has a roller instead of a hook at the end.

Just a very basic lock fitted to any number of low grade guns.

And no intercepting sears either--RWTF

somewhat like an elezze Smyth(Manufrankinstien.newby orleans,indiana.(Bet this helps,professor longhair,basement studio, York maine....

Great to hear from you David. Don't be a stranger.

Wow!! The Purdey man himself.

Since he worked so long on Parkers and wrote so many articles about same....could one now call him The "P" Man?

Ah yes, thanks Professor longhair from York

Interesting sear engagement, more acute angle than in sidelocks, closer to boxlock layout. Probably to counter the lack of intercepting safety sear. Simple but definitely not crude.

Gunman hit the nail on the head, as usual. Simple, low grade, back action trade lock probably manufactured in house by Tolley (1879 patent action) in Birmingham for sale to the trade. “Duck bill” style locks were seen as a cheap, out of fashion and not pleasing to the eye. Low grade does NOT mean low quality. The quality is still there...

excellent, I knew someone would know. Great lead thanks!! 1879 patent, out of fashion in 9 yrs?

Yep. Things were moving pretty rapidly by then. Scott & Baker patent action was pretty much taking over by then....and during that time frame..a flurry of action patents & ideas were blowing up the trade.

Awesome! Great info!

RARidell check your PMs.

Nothing there!
