Although it's not the same, I purchased a Pre-War S&W Heavy Duty that was once carried by a BCPP officer.
It was hardly shot, no rust, but has honest holster wear.
I would put the blueing finish at about 85%.
Personally, I did not mind paying 500 dollars for it. (for some that's too much I guess)
PS: If the ambient light does not beam off the half-moon front sight, it's a very accurate shooter. Double action pull is superb as well.
Finding fine qualities like these old S&W sixguns, in any handgun, is a rarity these days.
I am not a collector, my guns I buy to use them.
Edit: Any of these big'ole N-frames are real pussy cats with factory level power, 38 special.
Onty, your pictures display two different handguns BTW. Maybe you are aware of this?
