Sorry to resurrect such an old thread but I think I can shed some light on what this is.
I'm pretty certain these were made by Sogolee (in Taiwan?) back in the late 80's or early 90's , they are often sold in Sogolee boxes.
They were made and sold under various names including as said here Atlantis, Siki, Simons, Superior and maybe some others.
It's possible they were named and produced for Artshops to sell as their own branded airbrushes as DJ Simons is a big artshop on the Hackney Rd in London and Atlantis is also a big artshop on Bayford St London.
Yes they are a knock off but to my eye seem to be good quality ones. They use the same 1.5mm needles that Rich use as opposed to the 1.151mm needles used by the cheap Chinese airbrushes of today. The chrome is also good quality. They do seem to use a nozzle with a slightly larger thread than a standard Rich, if anyone can suggest a replacement it would be appreciated. They also came with instructions and a full parts breakdown suggesting that at some point you could get spares for them.
These are different animals to the Chinese AB130 airbrushes that are all over Ebay. Although I haven't had one to check it seems they use different nozzles and needles, they also have different castings for the body and are finished differently.
These were made in the same series as DaveG's Sogolee HP-101 featured on his Airbrush exploration page back in May. In fact the instructions were for the HP-101 on one side and the HP-102 on the other.
I have a couple, an AB300 which depnding on how you look at it is either a clone of a Rich AB300 or an Olympos HP-100c and one of these HP-102's
