Identification help needed MM Model AID?

The ID tag on this industrial tractor shows it as a model AID but that is not a model number for and m&m tractor. It may have had a backhoe at one time but it does have a loader. I will need to get some manuals on it but first got to identify it. Any help appreciated.

Looks like a Minneapolis Moline Big Mo 500 (possibly a 600). Check the Model/Serial plate on tractor and the engine and see if it says Motec or Mopower on it. Then get serial numbers off of the plates to check the year built. Built from 1960 thru 1966. The serial numbers of the tractor and the engine will indicate the year of manufacture -- earlier ones were Mopower or Motec on the plate.
 
It is a 335. Can tell by only 2 bolts in the grill (445's have 4) and no bolt on caps on the rear axles that 445's have. Also the step at the bottom front of the hood looks too wide to be a 445. If I remember correctly A1's are 335 and B1's are 445.

Thanks to all for the help, based on the comments and a check of serial number against model numbers on tractor data site it is a model 335 from 1957. I will dig in a little deeper. See if I can get her running.
 
If you need operators, repair, parts manuals --- Floyd county Museum in Charles City, Ia is the depository for them and they can copy them off and send to you!! Call Mary Ann there at 641-228-1099 at Museum for help and manuals. Good luck. If you need parts, let me know --I have a 445 for some parts an d can get you to others for points, pumps, etc.
