Lock ID needed

[mountainman]

Hi, I received this side by side double, don't know who the maker was, but the owner wanted me to check it, and go over it, to see if it was workable. So I looked it over and I noticed that the left lock does not want to stay cocked and then I discovered that somebody had replaced the main spring was that was not correct for the lock, the arch was too high at the toe and would come against the bolster before full cock.
I would like to order the right part for the lock if I could find out who made it, the internal has the letter S on it, the bridal and the sear.
I would appreciate your help on that; Thanks!

Maybe a Siler but there are several kits around of this pattern.Remove the spring and see if it will engage full cock and go from there.

It does engage, but with the wrong spring you can hardly get it to engage, you have to pull real hard to get the fly to move forward, there is not enough clearance between the spring and the bolster. I just need to know who made this lock?

I might have a spring in my pile that may work. I would need to confirm dimensions.

Is that oversize spring the same specs as large Siler?

Hi,
I doubt you will be able to buy a replacement spring to swap out the Siler spring put on the lock incorrectly.  I believe these are old Italian-made locks that used to be sold by Dixie Gun Works years ago.  They can be made into pretty good locks with some work.  Check Dixie to see if they might have old replacement springs that ft.  Alternatively, that mainspring would be easy to fabricate.

If the spring is not readily available, and you don't feel confident to alter things , you can always send the lock to Cabin Creek, {Brad Emig }  He'll fix it up for you.

A fine assembly of mismatched parts.A quick fix would be to find someone with a milling machine and make a relief cut for the main spring to go at full cock.

Make a relief cut on the underside of the bolster as Bob says.
If you look closely at the RH lock, it appears that it has a very slight relief cut for the MS at the breech end  . The LH lock doesn't have one.
Might have to enlarge the pics to see it better

Thanks for the response guys! If we need to choose options those are all good, but I believe it's better to find the correct part designed for the lock first if it's available, if not then we'll choose the best options, and go from there.

Thanks Dave, that was my thought too, that it may have came from Dixie Gun Works, but I needed a second opinion, that's going to be my first step is to call them, and we'll go from there..
