Mike, why does anyone do anything? :-) It makes you wonder. But, a different trigger guard, trigger, and internal mechanism, all together, along with dropping the flanged barrel, and the fluted comb on the stock, plus using a stamped rear sight, could make a difference in profit. Also, as I understand it, the guns were made to be easily afordable to the masses.
As to the display, these guns are not very popular and the judges really did not know what they were looking at. This past weekend I had a Savage display, "Savage Goes to War" at a military collectors show. Again, the spectators did not know what they were. I only had one person read everything on my table. While the two M220's on display were very rare, most people only stopped to look at the Savage made British Enfield. One good thing....as long as these guns are relatively unknown and not appreciated, we few collectors can continue to find them at relatively low prices! :-)
