  However when it came to part numbers Moto is
infamous for a plethora of

 was special for a project or customer.  Most of the other vendors did
 that as well but Motorola was wild.  HeathKit was a common consumer of
 house numberd parts from many vendors. 
Know of any good references for crossing some of this stuff?

None really as some dont cross "exist".  TO cross most I use a NTE or other
parts sub manaul to find out what it is then work backward to a usuable number.
tedious but near the only way to get from a M9313 RF transistor to a 2N or
MRFxxxx part number.
