I had a conversation yesterday with Nate Kiowa Jones (aka Steve Young of Steve's Gunz
well known for his work on leverguns for the CAS crowd) and he mentioned that he's
done some work with the Taylor Spencers. He feels that he has a good understanding
of the gun. Interestingly, he found that removal of one of the extractor hooks smooths
up operation of the gun. I've already forgotten which side, but one side of the part is
ground down so that it doesn't contact the case but still acts to align the part in the gun.
Anyway, here's another source of help if you need it. I pointed him to L. Romano as
well, although he had heard of that producer of Spencers.
