This one was an ebay purchase. The seller acknowledged that he knew nothing about them and that it seemed to shoot hard. I chronographed it about 430fps so no problem there. I did notice tiny particles in the breech and some deterioration of the conical blue seal so decided to check. Mr Slade emailed me this morning and said not to shoot it any more as without that piston buffer it might induce more damage to a bear trap, and increase repair cost, so I packed it up and sent it out.
When looking at pictures posted by the seller it looked to be probably 90-95% condition, no blueing wear no scratches, just some discolored areas on the stippling of the grips which were grayish white. I cleaned that with mineral spirits and a toothbrush, then applied some colored shoe polish followed by clear and the grips look great now. I think it will be a good shooter when I get it back, I did purchase it anticipating the need for new seals and possibly a spring, so no surprise there.
