Have an old Brazil contact 1917/1937. Sn# 171xxx. Round top, round bottom sights, serrated trigger. I think I paid $125 for it in 1993.
Some pitting outside of the barrel, but the insides are clean and the action is solid. Someone buggered up the knurling on the extractor rod. No reason to think the grips aren't original.
Thinking of having it cut off down to 3 1/2", the front of the cylinder rounded, the chambers chamfered, the action and internals given a decent going over and springs replaced. Finished with a nice matte blue finish.
Any reason not to?
