Help a newbie decode a motor
 

I have a 440 motor.
It is date coded 1-22-70.
The other numbers on it are: 2536430-7
OR, it might be:
2586430-7

I think it's the first set of numbers, though.

Please tell me what this is. Is it an HO motor? Any idea what it might have came out of?
Please help. I'm new.
