An extractor from the kit
http://www.sarcoinc.com/erma22.html part #8907 appears tantalizingly similar to the extractor in a KGP68
http://www.gun-parts.com/erma/Er%2068.jpg Part #25. I'm in the midst of creating a run of the latter, for a couple of my pistols that are missing the part, and ultimately some for sale. Right now, I have a few "blanks" which have been sliced from a bar of tool steel that has been milled to yield the approximate profile of an extractor. What they need is to be fitted by hand filing, heat treated, and then finished. In the meantime, I've sold a couple of the raw blanks for $15, shipped, and the Erma owners that got them have had success in fitting them, using a scan of an original as a guide. The next problem is to obtain the proper plunger and spring, both elusive parts. The plungers can be turned from drill rod stock, but I have not developed a source for the springs yet.
