OID for device type?

I'm trying to find an OID that will help my monitoring software differentiate between an AP and and SM so it can then give them different templates, but the usual suspects don't appear.  Any ideas?  I've loaded the current MIB file but I don't see anything that shows me a model number or device mode.

I think I found my answer.  In case someone comes looking.

oid=1.3.6.1.4.1.17713.21.1.1.2.0

Possible values=
-1 - Not available
0 - 5 GHz Connectorized Radio with Sync
1 - 5 GHz Connectorized Radio
2 - 5 GHz Integrated Radio
3 - 2.4 GHz Connectorized Radio with Sync
4 - 2.4 GHz Connectorized Radio
5 - 2.4 GHz Integrated Radio
6 - Force 200 ROW
7 - Reserved
8 - Force 200
9 - Force 200 FCC
10 - ePMP 2000 Connectorized Radio with Sync
11 - Force 180 ROW
12 - Force 180 FCC
Device Allocation: AP, SM

You can also use this one to define whether device is configured to AP, SM or SA mode:

.1.3.6.1.4.1.17713.21.3.8.2.1.0

wirelessInterfaceMode OBJECT-TYPE SYNTAX Integer32 (1|2|3) MAX-ACCESS read-write STATUS current DESCRIPTION "Wireless Interface Mode: 1 for AP, 2 for SM, 3 for Spectrum Analyzer Device Allocation: AP, SM" ::= { wirelessInterface 1 }

Thank you.
