Well I finished the first of the two carbines I bought. This one (go back to first post) is a post-war refurb that came in a well used M2 stock, and the receiver had the serial number re-stamped forward of the rear sight base when the flip sight was replaced with a stamped adjustable sight post war. The gun is in the serial range where it could have left the factory with either a flip sight or a milled rear adjustable sight.
I ended up installing a new Criterion non-restricted barrel and changed the rear stamped sight for a milled inland adjustable sight. I also changed the bayonet style front band for an original inland type 1 band I already had. The stock has been changed to a more or less correct low-wall oval cut WW2 stock and well matched 2 rivet handguard. This is actually an SG stock, so not "correct" as manufactured, but it's the right type of stock in decent shape and not over sanded.
I also changed the round IBM bolt that was in the gun for a late production inland flat bolt and headspaced the new barrel to this bolt.
The trigger housing that came on it was a type 2 Rock-ola with a mix of internal parts. I've swapped that out for an inland type 5 housing I had. I also installed an inland hammer. The trigger is still mis-matched (a Quality Hardware part), but I didn't have an inland one handy, so it will do. It also got a correct inland push button safety.
The type 5 slide had a badly worn guide tab, so I TIG welded it up and re-machined it back to original dimensions, so it now fits and functions perfect.
Considering the barrel swap and that this will never be collectible as an original, I can live with the few non-inland parts and I'm calling it done for now. Was debating re-parkerizing it, but unless I found a NOS M1 stock, I think it might look off with fresh metal and a worn piece of timber, so I think this is fine.
Probably more trouble and money than it was worth, but I think a good save from the ratty and worn Israeli surplus gun it started as. Of the two, this was definitely the higher mileage of my 2 rifles.
