Today in the mail my Luger frame was returned from the machinist with the once ground-off lug replaced. Broke out the stock and was very pleased with the result. This going to be a smashing addition to my collection. Because of the ground-off lug, I got this piece on gb for less that 1.2k, and it was really in excellent condition other than the lug.

Believe me, the upper alone is worth close to 2k as it was 98% with an almost new bore. Now, I have get the lower re-blued. But I have a concern. I have considered heating the lug with a propane torch and quenching with oil. Not too hot, just maybe around 600 deg. Any opinions about this would be much appreciated.
