It's probably one of those modern Mauser Hi-Power clones. They made a single action and a double action version - I think it was called the model 90(?) - possibly made with unlicensed-copy Hungarian (FEG) parts. They were in the gun catalogues for awhile, then dissappeared, several years ago.
However, based on Mauser's reputation alone, I think if I saw one (the single action version of course) at the right price I don't think I would pass it up.
