Dave, if you do work on those guns, please provide your name and address as most gunsmiths won't touch them. Just too much trouble for too little reward. The same is true for the old DA revolvers (H&R, IJ, H&A, M&H), so if you work on those you should have plenty of work.
In my experience, blowing up is not a common problem with the old guns; broken springs and worn parts are the real problems that usually result in the guns being tossed in the junk pile or kept for a turn in program.
