Any and all measurements please? Mine is #149 so there is some time between them, but mine does have the adjustable trigger. (Well, I think it is adjustable, there is a screw on the bottom of the grip that seemed to tighten the pull if memory serves.) I had all the parts when I inherited the gun, took it to a gun smith when I noticed the hammer didn't seem to cock. Sure enough the lip of the sear where it catches the hammer was gone. (Looked like it got a bit to hard and broke off some time over the years). I swear it was put back together then. Fast forward a decade and I decide to take it to another smith... lo an behold the sear was not in the gun.
