"There may be some 'vintage' value to it as well."
Unfortunately, not really. All three boxes are pretty badly battered, and non appears to be full. All are post 1930s, and very likely post World War II, although it's hard to tell exactly.
The most interesting box is Remington Police Service load. Unfortunately, it's the lead bullet box, not the more desirable metal point bullet box.
IF there is still original ammo in each box, as opposed to fill ins or nothing at all, they might be worth $10.
As for the revolver, I agree that it's older than World War II due to the mushroom head ejector rod, although it's not uncommon to find that on guns right up to the eve of World War II. When the depression hit, S&W had a HUGE backlog of parts built up and suddenly no sales.
Parts made in the 1920s were used to fulfill the first of the British orders in 1940-41, including, I think some of the mushroom head ejector rod caps.
Hiprolllc, what's the serial number on your gun (found on the butt). Use XXX in place of the last few digits.
