Dunstall and other alloy cylinders

A question: Do all Dunstall barrels say "Dunstall" on the front? I know there were some other ones advertised in the Norton News years ago under the name of Left Coast Racing. I see that name and logo on the Steve Maney website. Were there other alloy barrels back in the day, that were widely available? I have what appears to be a Dunstall barrel (on the bike), but it doesn't have the name on it. PO assumed it was Dunstall. And, I was well aware of the issues ans shortcomings of them before I bought it. I just always figured if it gave me too much grief, I'd dump it, and use it for a pretty paperweight. So far, so good, but that could change this afternoon, if you know what I mean.

Thanks Ken! BTW, I've read your "why badmouth Dunstall" thread before. Very interesting, and the pictures tell it like it is!
