Well, i do know it is a genie, i didnt have a flashlight handy and the plate has been pretty weathered but i should be able to read it with the proper lighting. will update you guys further when i get home tonight.
This beast is old enough that i believe it was produced before wireless units...
I just bought a house with a detached garage with a very old garage door opener system. The unit has to be at least 30 years old with the straight bar system. I'll grab a make and model when I get home. I'm looking for an adhoc wireless garage remote to add so I don't have to get out of my car...
