That is certainly true and it is also significant that Colt and Winchester are long recognized and respected names with strong brand identity. Brand identity enhances their collectible appeal. Speaking of low supply look at the Colt Boa, which can be bought for about $4 K each, and rising.
"Two variants of the Python were made in small numbers by Colt. The first was the Colt Boa of 1985, which was a limited production revolver, also .357 Magnum caliber, made by Colt for the Lew Horton Distributing Company in Massachusetts. It resembles closely the Python. Six hundred 6" revolvers and 600 4" revolvers were made, of which 100 were matched sets. Though it resembles a Python visually, in order to keep its purchase cost down it is substantially different internally and required less hand fitting. The second was the stainless steel Colt Grizzly of 1994, another limited production .357 Magnum revolver. One thousand two hundred of these weapons were manufactured, half with 6" and half with 4" barrels. The Grizzly had smooth, unfluted cylinders".
