Retrieve PMP Part Number with SNMP

Is there a way with SNMP to retrieve the part number of a PMP device? Closest I have found is boxDeviceType.

I want an easy way to see if its PMP450, PMP450i, PMP450m, PMP450b, PMP450d, 5.xghz, 3.6ghz, etc.

This may have been covered under a post of mine just recently. Check it out HERE.
