I was thinking of Lyle today and thought about checking to see if he was on the forum. As far as his disappearance from the S&W forum, I can only guess that it might have had something to do with moving up in the corporate world and the incompatibility of being an out of the closet gun collector in the politically correct white collar end of business.
I can comment though on my experience in dealing with him on a revolver transaction.
I was fortunate enough to get a Model marked Model 20 S&W 4 inch Heavy Duty Pueblo Colorado PD revolver from I think it was KY imports.
I posted some stuff on here about the revolver, Lyle contacted me, and wanted the revolver. At the same time, the premier 38/44 HD collector here on the forum contacted me and advised me to beware (I wished I had). Coincidently all three of us are or were Army Officers.
Not being a collector but a shooter a deal was struck where Lyle and I would trade guns. I would get a very good to excellent 38/44 Heavy Duty post war Pueblo PD revolver, plus (if I remember right) a $100.00 bill, for my very-good to excellent Model 20 marked gun. The deal was done and what I received was a worn out (cylinder stop notches slopped / peened over, a heavy tracking line on the cylinder, heavy shell casing wear on the recoil shield, out of spec BC gap, excessive end-shake, and an ejector rod in the white, finish worn slam off) Heavy Duty. Well, what the heck. So I talked to him about it, and he insisted the gun was as described.
So lemons and lemonade, I thought to send it in to S&W for a refurb and re-blue. So I shipped it into Smith & Wesson, and I was contacted by Gene, the man working at S&W repair at the time. Gene tells me one chamber of the cylinder is blown, the gun is not safe to shoot, and the window / slot in the frame where the cylinder stop protrudes is enlarged from heavy use, impossible to return to factory spec, but he could peen it enough to make it functional. Gene went on to tell me that he'd have to replace the cylinder, but he'd have to use a 27-3 cylinder in .357 because they did not have any HD cylinders left. I declined the repair and had it sent back to me thinking you can't polish a ****. I ended up sending the gun back to Lyle. He did not want to return the Model 20 to me, so I agreed to a cash payment for my gun. If I remember right, I think I ended up with $600.00 total.
On a different note, a great friend of mine purchased an advertised "LNIB" S&W pre-lock 640 from Lyle through GB. When he received the gun, the cylinder had a heavy tracking line and the cylinder would not cycle when the trigger was pulled, it was so fouled up with black gummy carbon & grease. Being a do it your-selfer, my friend flushed & cleaned the internals, lubed it with break-free for use, and it turned out he had a 640 with a slick DA pull that he was happy with.
Based on those experiences, I don't have much respect for the guy.
