It's usually hard to find information weird brands like these, but I just wanna say that that's a really cool tuning wheel design!
But the L-R separated volume control is very impractical (IMHO). Also I don't think it's a brand, but more a promotional thing made especially for Camel.
Nice find and you won't find a lot of information on it. Most of the units from Hong Kong and Taiwan were made for other companies and stores to put their name on and resell. We used to get catalogs in the old days were you would buy something like 100 of these and the manufacturer would put whatever label you wanted on the metal plaques. Most of them ended up in smaller stores or used as a freebie when you bought a full stereo system.
