Here is a photo of the three iterations of the rifles. Remington 600 on top, gussied up stock and a 2" longer barreled Model 660 in the middle, and the Mohawk on the bottom.
The original Model 600's were chambered for .222 Remington, .223 Remington, 6mm Remington, .243 Winchester, .308 Winchester, and .35 Remington. In addition, a "Magnum" version was offered in 6.5mm Remington Magnum and .350 Remington Magnum. These Magnum 600's came with a laminated walnut stock, recoil pad, and sling.
This is what the back of the Mohawk 600 action looked like with the word "Mohawk" plainly engraved there. The action did not say Remington on it as the Mohawk line was a promotional line that was introduced first by K-mart, IIRC. The original Model 600 actions were engraved with the word Remington in large script with "Model 600" below it in smaller print. The Model 660 was the same with the word "Model 660" in smaller print
This last photo shows the original box and a Mohawk rifles as they both came from the factory. Notice again the lack of "Remington" on display.
If your father's "600 Mohawk" is a true Mohawk action as I described with a vent rib barrel, either it has been modified by someone or you have a rare bird that might be worth beau coup dollars. To get the big dollars for it, you would have to be able to prove it came original from the factory that way. That might be quite a task. Odds say its been modified if it is indeed a Mohawk action and not a Remington 600 action.
