I snagged these off of that auction site for less than a hundred bucks. They were listed as "Old School Gasser Knockoff". I don't think they're Cal Custom. They are cast and the chrome is in excellent shape. I've never seen these before, not even in old catalogs. I'd like to know what era they're from. The only brand marking I found was a tiny little "dcp" logo. I have no clue what manufacturer that is. Maybe some of you guys can help ID these. Thanks. The brakets come in pieces and can be configured to 4.75 or 5. Here they are all set up. Check the key lock. Pretty nifty. Here's a shot of the "dcp" logo. It's tiny.
