H&R Trapdoor Carbine parts?

[Doc Holloman]

I picked up an H&R carbine on Gunbroker to back up my Pedersoli.  Put six rounds through it.  On the 7th round, the cartridge rim started slipping behind the extractor and the breach would not close.   Had to get the round out with cleaning rod. Happens every time I try to load it now. 

I took a close look at the extractor and the end of it is quite worn, maybe even having a small bit broken off. 
I've been looking for a replacement extractor, but H&R parts are pretty much dried up. Not sure if the original Springfield extractor or the Pedersoli will fit.   Even those look hard to find -- out of stock from the usual sources.  Google searches for the part just seem to get me a lot of hits for broken case extractors, obviously not what I need. 

Any advice?

Best to look for an original.  S&S also has new ones made. https://www.ssfirearms.com/proddetail.asp?prod=73S207A   It will either drop right in, or simply need a few strokes of a jewelers file.  Many of the small parts on the H&Rs were original parts, your extractor may well have been over a century old.   The Pedersoli would most likely fit as well.

FWIW seems like someone is always parting out a trapdoor on Ebay.

I don't know if they still have any, but years ago I broke an extractor/ejector and bought several repos from Dixie.

I got a repro Springfield retractor from S&S.  It was oversized compared to the H&R part and required quite a bit of filing and fitting, but I eventually got it in.
