I also have an early RCA universal remote with the number 97P04730 stamped on the battery cover. I do know if that is the part number for the remote. There are buttons labelled TV and VCR, presumably to select which device the buttons will work for. This remote has a "search" button, but no "code search" button that is found on later RCA remotes. I have spend several hours searching the net for any information on this device. The only thing I found was a post that claimed this early remote is programmed by pressing and holding the device button (TV or VCR) and simultaneously entering the device code. Because this is a very old remote, it probably uses 3 digit codes. There are several places that list RCA 3 digit remote codes. I have tried to program mine this way, but I have not been successful. Possibly my remote is not working correctly, but it is putting out IR.
