The thread is old. The guy selling the parts did not start the thread someone else saw them on CL and posted the thread. The guy selling the parts is selling a warehouse full, not an individual part. The two guys chatting were not the guy selling the parts. Hence my suggestion--I think if you want someone to see your parts request, it would be a better idea to start your own thread in the parts wanted section.
I've emailed the guy about a couple of parts, one of which he says he has (the back door for my Jennings Bronze Chief). He also says he has about 20 machines for sale, in addition to parts. I plan to go visit his shop next week.
I went to visit this guy's shop today. Attached are some pictures of restored machines he has for sale in the front part of his shop. He has what he termed "more than an 18-wheeler full" of parts in the warehouse section of his shop. I went back there with him to take a look, and I'd say it's at least that much stuff, and likely more. He says all of the parts he has are Mills and Jennings, mostly Mills. He tells me that Mills made and sold a lot more machines than did Jennings. I bought an original back door from him for my Bronze Chief while I was there. It's definitely an original... I'll have to clean it up and paint it myself. The existing door since I've had the Chief had been fabricated by someone in the past... someone whose last name wasn't Jennings.
