I had 8 Laminate stocked 91/30's out of 20 from a crate of M91/30s that I bought a few years back. Sold them all to a guy who was dying the laminates to "pretty" colors for re-sale...
They are post war replacement stocks, not really "more" collectable IMO unless someone wants that variation of course. Though, still kicking myself for passing up a 1947 M91/30 Sniper with a Laminate stock because I wanted a "wartime" dated Sniper....
Have seen many M38s and M44s with Laminate stocks too, and while they look good and may have that "Vietcong" Cache, I'd rather have something more in tune to what was used in WW2.
YMMV
I do agree with "bearhunters" observations, is that people will pay more for "pretty" rifles, no matter if "original' or not...
