ID this lock and mainspring help

[Wawyasto]

I'm trying to idenify the lock on my 24 ga trade gun. I bought this used a couple months back and the lock is much slower than my caplocks and Pedersoli Mortimer rifle. I'm a noob with flintlocks so I'm sort of flying by the seat of my pants here. Do I need a new mainspring or can the old one be reworked, thoughts?

If the mainspring seems to have good resistance when cocking the hammer it is probably more of an issue of smoothing and lubricating all of the surfaces that move/touch each other. It looks like it could use a good refurbishing.

Could be a North Star West lock. Probably as rough/smooth and slow/fast as originals, which on trade guns were mediocre quality. As above, polish bearing surfaces carefully and get some oil on it and see if you can get improvement. Ignition speed on a flintlock is also dependent on your touchhole.

The stamp on the lock looks like a Sitting Fox Muzzleloaders touchmark. You could try contacting them for parts, although I would try previous posters suggestions first.

looks like a north star curley lock. needs smoothing. parts always seem to be a little rough.

Is that a crack that I see in the mainspring?
Shows better in the larger pic.

It looks to be a North Star Enterprises trade gun lock made in Dayton, OH by Curly Gostomski, probably from the ‘80s.
You can see just a bit of the North Star logo on the inside of the plate.
Curly was a mainstay in the muzzleloading field for many years and was known for making Trade Guns and triggers, nipple wrenches and other muzzleloading accessories.

scott,
Your mention of Curly Gostomski brings back some memories, I met him back in the 1980s (iirc) when he visited Australia, a most interesting bloke and likeable.
