Post the serial number. Leave the last couple digits as "XX" if it makes you feel better.
The reason is that you're claiming it's an as new in box 1979 Model 36 no dash, when you're showing it with a box that S&W didn't start using until 1983.
A 1970 should have the two piece "Bangor Punta" marked box used from 1966 to 1985. Blued revolvers in the era came in blue boxes while nickel plated revolvers from this era would have come in a gray Bangor Punta box. These were the same boxes used from 1957-1966, just marked "Bangor Punta" or "A Bangor Punta Company" printed between the Smith and Wesson and the Springfield Mass address. In the last couple years of use you may find them marked "Lear Siegler Corp".
S&W didn't start using the one piece boxes with tuck in wings shown in your picture until 1983, over lapping the two piece boxes for a couple years. If it were a 1983-1985 revolver in a Bangor Punta box it would be understandable as S&W used up existing boxes, but it doesn't work the other way around for a revolver made prior to 1983.

In any event, even with an original matching serial number box, it's probably not worth more than $600 or so unless you find someone who really wants to fill a hole in a collection.
