Need key to unlock oak rolltop desk with this name on the lock. Put the top down, and the top and all drawers but one also locked.

Have you checked to see if the company is still in business... if so, they MAY have a record of the lock and be able to provide some direction. If this is a quality desk (sorry, I'm not familiar with the maker), it will probably have something like a 5-pin Yale-type lock. If you can't get satisfaction from the manufacturer, you could try picking the lock (not as easy as on TV, but not too hard, either--look on the web for directions). Sometimes you can slip the catch (between the desk top and the roll-top tambour). Since the desk locked by itself when you put the top down, there should be a spring-loaded catch on the roll-top portion. If you could give us a photo of the lock area (probably lap drawer and bottom of tambour) there may be more help available.
