Actually...I think those grips were on it when he got it. Are they not Colt stock?!
Those are stock.
Yes, some came with factory Pachmayrs.
The way they are trending, they’ll hit $3000 soon.
It’s your Dad’s gun, if it had been left to me I wouldn’t sell it for any price.
They are, and anyone shooting it for competition (it is set up with target sighting) will want them. BTW, a "nickle" is a five cent coin, but the metallic coating is the element "nickel" (from the German 'kupfernickel,' Satan's copper).
This gun is a treasure to be passed on to someone in the family who will prize it and take care of it. It was (past tense) one of the finest double-action revolvers ever produced. It will doubtlessly just keep on increasing in dollar value as an investment if it is not marred by wearing it out in shooting, poor cleaning, or inept disassembly with poor tools. See:

Maybe they're OEM Colt grips made by Pachmayr. Wood grips would look nicer, either way.
