Ah, nice find. Some other brands did that too with their remotes. It seems a really common, relatively simple model remote. Chances are that most Mitsubishi remotes of the era will be compatible.

There might be useful information on the inside, but we're not nearly done with the outside. There are texts on the front, buttons, there's a serial number on the back, etc. So many details that say something about the set. I don't remember without seeing how Mitsubishi serial numbers work, but it may give clues about both the number produced and the production date.
