Ren, while your observation "may" be correct, (I personally actually agree as it does look "slab sided", a typical characteristic of TRW stocks) do you have definite proof or info from Kelly, Lynne, or Josh at McMillan that they did in fact pattern the early Mc stock off of a S.E. Overton, or TRW stock? If not, please retract or edit your statement before it becomes "internet bible" info.Your USMC rifle is a master piece of hard work and dedication…she is a beauty.
I would like to point out that your stock was patterned from an S.E. Overton stock or better known as a TRW slab side stock. If your interested take a look at the picture I posted of the USMC TEAM RIFLES. You will notice the flats on the stocks with the same smear pattern as yours here in this thread. The other three rifles do not exhibit this feature.
Just thought it might be of interest.
