I had a fragment of the Lefever records that I got in Pennsylvania at a book shop about 30 years ago. It was bound and contained some production records and some records of returned guns for repair as I recall.I advertised it in the Gun List and took it to a couple of gun shows with a price of $400 I believe. Zero interest. I finally traded it for a nice antique carpenters chest and some tools as my son was interested in woodworking.Don't remember much about it but it was far from complete and I speculated that someone just wanted to preserve some of the records that probably worked for Lefever.Never could locate the guy who ended up with it once I found out that it had some real value but he lived in Illinois and I believe his last name was Wilson.I hope I don't regret bringing this up as I took some "flak" at the time. My interest was mainly ephemera of all kinds and this was interesting.
