This probably is not news to those who know, but Jack First's early, long 39 extractors are most excellent.
A local FFL friend, (with a "store front,") got a 39 in. It is in OK shape but of course all of the extractor assembly was gone. He asked me to fix it as he couldn't sell it as is.
Anyway, I checked/called the usual sources, and Jack First had it all. The great women I talked to knew so much, and set me up. I got the parts in four days. They are making these in house, as well as the 52's. ( Maybe the same part ?) It "snapped" right in, and the 39 functions perfect.
I actually found the original, rear lower part that hooks in, stuck in the de-cocker, and it appeared deep blued, where as the new replacement is not.
If needed, we should support Jack First so they keep supporting us.
