Well, they both use the Series III OPT Targeting & Tracking system.
Some of the technologies are different generations though. like, the Comm Suite is a Khan Series Type 2c on the Timber Wolf, but a Khan Series Type 1 on the Orion IIc. Type W3 Endo Steel Structure on the Timber Wolf, Type W2 Endo Steel on the Orion IIc. Interestingly, the Armor Composition reverses that. Timber Wolf uses A-2 Ferro Fibrous, while the Orion IIc uses A-4.
The reactors are completely unrelated. Starfire 375XL versus Heavy Force 300 SFE.
Weapons-wise, it's ambiguous. all of the Orion IIc's weapon types are used on one configuration or another of the Timber Wolf. Gauss, SRM-4 on the B, ERLLs on the Prime and C, LRM-20 on the Prime. They COULD be the same models, they could be different. I doubt we'll ever really know. 3050u does not give models for the guns.
What strikes me, is that the Republic apparently builds some Orion IIcs and the respective clans wolf do absolutely nothing about it.
