Mamiya Part Number Indentification

I have some Mamiya replacement parts that I can't identify which camera they belong to. Does anyone have a list of the Mamiya part numbers and the Mamiya cameras that they relate too.
Example: What camera does Part # 5071-61161 (ARSH-6116) Film Roller belong to. I believe the part # 5200-xxxx relates to the Mamiya 645 cameras.
Any help would be appreciated.

I don't think you are going to find an online resource for Mamiya part numbers as the number of parts is quite large and I don't see that getting digitized. While I do have the master parts list printout for Mamiya it is a one inch thick book with around 20,000 part numbers! Oh, the 5071 part is for an RB67 PRO S back.

Here's an interesting source.

Thanks to both of you for the information. I have a lot of parts for the Mamiya Press series of cameras as well as a few that were identified as for the Mamiya 645 series. I wasn't able to find anything that would put a name to the 5071 so thanks for linking that that number to the RB67.
Thanks again
