I don't know the part number, but it's a fairly large square hand unit with a smoked plastic pop-off cover for VCR controls. The clock and channel programming is under a secret cover that is HARD to snap off at the top front of the unit (use two thumbs to press the cover down & away from you, while holding the remote). If yours is the Dimensia version, it also has buttons for stereo, CD deck, etc. The remote on my wife's 19" RCA is very similar, and in fact may be the same as for yours. You can barely see it sitting on top left of the tv in this pic:
