USMC 1909 Revolver question

I picked up a USMC revolver #139. It has been professional reblued, looks almost like a arsenal refinish leaving most stampings in excellent shape and no buffing of corners but alas, still a reblue. My question is that it came with two pr of grips. Original wooden ones, and the black plastic ones with the Colt logo. Both these grips are made for and fit the rounded butt of the USMC 1909 and will not fit the Army 1909. My first question is, are there other revolvers that have that type of rounded back heel that these grips would fit or would these grips fit only the USMC 1909 revolver. Question 2, I read that the early USMC revolvers had the plastic grips and then the woodened ones. Is serial number #139 early enough for the plastic ones? I paid $450 for the gun. Any ideas of the value even though it's been reblued. I wish I know how to post photos here. Ray.
