Okay guys. Wanted to give you an update and my thanks.
I don't actually have the pistol in hand. I merely started the thread out of curiosity and to see if it would provide some insight.
After speaking with my uncle it appears that after the chamber has been cleaned well, and a little polishing, the pistol will now shoot several rounds before FTE.
He did replace the extractor and immediately had to file on it to get it to fit as it was much too long.
He contacted Dan Coonan and apparently this model B was produced/made after Dan was gone from the company. Dan Coonan claims this particular pistol has had the slide drilled incorrectly and that's why the replacement extractor doesn't fit. Dan told him if he found a machine shop or gunsmith that could make him an extractor, that he would provide the measurements needed.
Thanks to all that responded! It appears this particular Model B is an "in-between" year.
