Marvin... true enough.... I just look at it from a car guys point of view, where I like all numbers to match... but I suppose you're right in this case where a cabinet is just a cabinet etc...
Ezra, as for getting the 81 Id tag, then trying for the machine.... that's kind of like getting the ashtray for a 64 mustang, then trying to get the rest of the parts to build the car. I wish you nothing but luck, but it's a hard task with searching, travel, transport, shipping etc..
