Bob asked me to post these images for him.  I trust he'll add some commentary.

Thats a Davis "Twigg"  I put Bob's version on sons 16 bore,  what an improvement.   Tom

I appreciate your enthusiasm, John, but I suspect the lock is previously spoke fer!  But, maybe not!

[JTR]

I expect it's spoke for too, Taylor. But maybe not. And if not, I spoke!

And whether its for sale or not, it's nice to see Bob's work!

 The first comment is thanks again Taylor for the help. I am thinking about maybe 2 to 5 locks a month for as long as I can make them. I hit 79 on the 27th of March and still feel good.New glasses on order. I have wondered about rebuilding existing Twigg locks so if anyone has ONE I can use for a guinea pig that is not
case hardened or engraved and want a better level of performance,let me know.The one pictured was made
as a new lock on the Davis/Twigg external parts which seem to be quite good.The mechanism shown is one
I developed for the Chambers Late Ketland and is basically a Hawken caplock mechanism with minor modifications.
This lock is sold to a man in Ohio who says it's for a grandson.On a REbuild I'd estimate the cost at $175 due to having to plug the existing screw holes and maybe level the inside of the lock plate.
I can be contacted at <bobroller@frontier.com> if someone is interested in a remade lock.

Bob, I'll gladly take another Twigg.   ..Tom

I would buy a new Roller/Twigg, and probably most any other late 18th century English/London style lock.

Glad to hear you are feeling well, and hope you continue your endeavors. Thanks for sharing your knowledge with us.

HECK...Looks like that stirrup is too low, and the sear bar is too high, the face of the frizzen is not PC and there are spru marks on the hammer............

ahahahhaahahaaaaaaaaaaaaaaa.........................

nice work Bob, I bet you like putting them tiny tiny threads in these locks...those internals look as if you might needs a 'cuss jar' close by..........

No cuss jar needed.This work,while labor intensive is not that difficult.The small screws are easy
and that includes the one that holds the link to the mainspring.I specialize in nice mechanisms and leave the polishing and parting lines to others.The Twigg is an elegant lock and with this mechanism,along with the other more elaborate ones I made can be a good performer.

My Twig/Roller is #4.  It's not in a gun, but deserves a nice fowler.

Bob, I was thinking about tiny blind holes.......my "baine" when I have done some on rifles!
Your locks are nice....keep working as long as you can, I visited mom this past weekend....she's 80 now, and a few stiff joints are there, but she cleans a couple of rich people's house to keep busy, and make gas money....mows here own yard, paints the banisters etc......we both are to nervous to just sit and watch the "boob tube"......so keep doing stuff.....just throw away the alarm clock!!!....

Dang life......just when you get to the age of knowing "stuff"......the joints won't let you do it!!!

Although, I knew at 30 NOT to carry the shingle bundles up the ladder......let them dumb 16 yr olds show off
