Goodyears?
I don't know about bad years or good years on these guns, but I had one and have also seen a few problems. Make sure you get the proper wrench for the barrel nut. Check to make sure the nut is not too burred from useing something else to remove it. (You can order a set of other colored sight blades). Remove the barrel if possible to check and make sure it does come out cleanly. I have seen one that was neglected and the barrel and nut were rusted, and the barrel jacket was rusted to the barrel and was hard to remove. Also check where the firing pin comes thru the frame and make sure there is no burr standing up from peening by the pin. There is also supposed to be a feeler guage with the wrench to set the barrel/cylinder gap. Otherwise check the action like you would on a Smith or something equivalent. Prices seem fairly nice if the appropriate accessories are included and there are no problems. You should find the gun to be very accurate, about target grade, unless there is a problem.
