BlueChipper, It's not a spam site. It links to a PDF document by Kevin P. who I'm assuming is Kevin Pennell as referenced in the napco4x4.org link. It's an interesting read, and not necessarily "garbage history". Without first hand evidence, it's all suppositional information.

You seem to be a bit confrontational, and it might help if you toned that down a bit.
I don't open links with .ru extensions as a rule. I don't trust them. I have no problem opening links from napco4x4.org, as I'm very familiar with the site. I know the history that was written by Kevin Pennell, and I'm quite familiar with his contribution to the NAPCO world. I'm also quite familiar with a lot of the developments and information that has come to light since that history was written.
I do tend to get passionate about these things. Confrontational? Maybe. But only if someone is trying to BS me. I'm sorry but Bart's assertions and assumptions were flat out wrong and I'm not going to let that become part of a searchable internet record without challenging it and correcting it as best I can. The internet is forever and once something is posted it is in a way legitimized. Example: We've all heard the guy at the car show swear by God in Heaven that his uncle Leeroy worked the line and was able to order his 1954 Chevy truck with a 283 brand spankin' new, or some other variation of that and I see it online as well. We all know how many holes there are in that statement, but people with less experience will believe it because they don't know any better. Then they'll repeat it. Repeating false claims has a way of legitimizing them. To suggest the because Jim Carter's catalog says the badges are unique to 1957-59 makes it gospel truth, purely for that reason is crazy. There is far too much actual evidence to the contrary out in the world.
Bottom line, I have been actively involved in the NAPCO world for a long time. I know what I'm talking about because I've hunted down the proof and had the parts in hand and crawled all over the trucks and owned several of them. I've never been satisfied with hearsay.
My first love was 1954 Chevy trucks, and I've always admired Tim Lederman's deep knowledge of them, which is based on a LOT of documentation, and a lot of first hand observation. Getting to ride in his 1954 Carryall at Macungie, Pennsylvania in 2007 is still one of my favorite memories. I've followed his lead of looking for the evidence in my 1954-55 Chevy research and my NAPCO research, both in the field and in the books.
In my experience on this site, there are a number of people that enjoy picking fights, and I'm not one to back down from them. So maybe it's not just me that can be confrontational and needs to tone it down.
