In theory, you need to have the patent number on it if you claim 
patented, but there's plenty of examples where the mfr doesn't do that.

It could be a design patent, too (they tend to be very narrow, but at 
least you can claim "patented").

However, none of the easy searches turns up anything likely.

If the patent issued in the mid 90s, then it would be expiring about now 
(assuming the patent holder has paid all the fees. otherwise it would 
have expired ealier)
