need 2nd model top break rear sear, hammer, grips

[old top break]

I have an S&W 2nd model 38DA revolver nearly complete, cycling in DA mode but need the following parts:

rear sear

grips any condition, must have nut and escutcheon inserts to bolt them on

possibly a hammer

the problem I have is, the rear sear I have is obviously too large to work in this model gun, and the 2nd model must have taken a smaller rear sear and/or different hammer- because a 3rd model sear won't work- there's not enough room in there for it to operate

I have read Numrich's diagram and they do list an "early" and "late" sear, so I'm thinking I need the "early" sear, as this also has the early model bolt stop and trigger

any help appreciated, if you have a SECOND MODEL parts gun PM me on this message board, or email [email protected]

could also use a BOLT TOP SPRING- a tiny coil spring- that goes in same gun as I made one that works for now, but would prefer a real SW part
