Unless TRS has the item ready to ship forget it. Unless the builder is extremely experienced and willing to spend LOTS of time forget it. Be sure they know what they are getting into and have done TRS "kits" before.
I have assembled two TRS Bakers. They soured me on TRS kits.
The parts are crude. The metal parts are made from casting made from original parts. They are smaller than the originals.
The wood is worse, really terrible. The first stock was not usable. I bought a second stock and the same panto-graph mistakes were present. The panto-graph master is flawed on the Baker master. No effort seems to be made to fix the problems. I even told TRS that there was a problem, I sent pictures. The second stock was messed up the same as the first. The master seems to have damage and wear that has not been repaired. With some serious head scratching and creative work arounds I made that one work.
Is it possible to make a nice rifle from a TRS Baker kit, yes. IT just took me way to long due the flaws. It will it take lots of extra time working around problems created by TRS.
I assembled one lock and made a decent working lock. I made a new tumbler from scratch and ignored the cast in spots to locate the holes. The other lock came assembled for me. IT was not a good lock. The mainspring was weak, bent and dragged on the lock plate. The fit of the parts was sloppy. The screws and tumbler were not located properly.
I have only shot one of the Bakers. Accuracy was dismal. The bore was rough and had very tight an loose spots. The inside of the muzzle was larger than most of the bore. It took me many-many hours of lapping to get it to shoot acceptably well. In hind-site I should had turned a better barrel and scrapped the first one. I would not use another TRS barrel without knowing who made it and inspecting it with a bore scope.
The TRS guns I assembled seem to be more suited to the historical re-enactor than a serious shooter.
Sorry to be a "Debbie Downer". Maybe others have had better luck.
