I'm guessing you're referring to the floor plate and set triggers? The rear sight looks like an early Pacific? I think I'd dispense with that unless the holes aren't usable for a Lyman 48. The barrel and front sight are interesting, the ramp is a Sedgley? And I saw the S stamp on the barrel, does that also signify Sedgley?
Unfortunately, it looks like someone buffed the bejeezus out of it when they reblued it. I'm assuming it came over as something other than an 06, since it's missing the cutout on the front ring.
