Update.
Well my Burgess is up and running again. Disassembly and reassembly is quite simple and have done it many times at this point. My machinist still has not completed replacement extractors but as good luck would have it, a receiver and bolt with unbroken extractors showed up on GB which I got for $52. Using both of the "new" extractors did not work but using the one good original extractor and the opposing "new" extractor did the trick. Can't wait until dove season.
