I owned a gun shop back in the '70s, and the list prices of most S&Ws were as shown, but - even dealers couldn't get any of the more desirable S&Ws, as they were in very short supply, and the distributors played games with their "allocations." In other words, you had to buy $2,000 - $3,000 of "garbage" inventory (cases of ammo in calibers you wouldn't sell in the next 50 years, arctic-level parkas we'd never sell in the desert, etc.) to get one gun. I just about couldn't get any guns (S&W or Colt, especially) that I could sell from any of the distributors "authorized" to sell to dealers in Arizona, had to go to a bunch of distributors in the midwest, south and east to get anything (and I had to buy a lot of other stuff to get them, and it was still difficult to get 19s, nearly impossible to get 27s, 29s, Pythons, etc.). The wild "Dirty Harry" demand was still in place for 29s, and $268 was a pipe dream, with used 19s going for $450-$650, and most dealers, if they could get one, priced them at $500 and up (I didn't, but, then again, only received one or two 29s over a 10-year period, and only one 27 - just couldn't get them). Yes, those prices sure look good, but if you wanted anything other than a Model 10, "lotsa luck" even finding one. Oh yeah, the stainless guns also were nearly impossible to get, and prices were significantly inflated on them, too. In fact, as I recall, even after playing the "allocation" game, the desirable models of S&Ws were often priced by the distributors to the dealers at well over the suggested retail price - not a good way for the dealer to make a profit when customers came in expecting to find a gun priced at retail, and the dealer had to pay more (sometimes MUCH more) than the listed retail price.
Ahh, memories!
