Gaylord Accessory "Knock Offs"... Anyone ever heard of these?

Recently came across these Gaylord "knock offs" in a pile of parts. Anyone know anything about them? They appear to be cast pot metal.

I only have 2. Would be interested in another pair potentially if someone has a pair.

Thanks, JH

I believe it's the same company, as they used to make a bunch of different parts. The owner, Bill Gaylord, might have some info for you, but he's not in much these days. He does eventually answer e-mails, though! haha

 

I have 4 NOS like picture , would like to know more myself ...
