This sounds like an interesting motor. It has been a while since I have done work on a 1453 so I can't remember exactly what the motor looked like. By the sounds of it you might have a modified Super J motor to begin with. It sounds like the lux designers might have decided to take the Super J motor, remove the gasket, then attach a mounting plate directly to the fan housings. Do your fan casings have bolts like on the 1205 motor? What is the diamiter of the fan casings?
I'll be interested to see what you think of your 1521 when you get it. It should have a nicer feel to it than your 1453. It will have a bit more metal on it and might also be a bit larger. You could also have some fun with the Automatic control.
Lastly, about that digital camera of yours. I might be able to help you with that. I "build" computers as a hobby so I can probably figure out what your problem might be and what you can do about it.
