Looks to be a first generation. The SN will date it if you have that. The box is a nice addition but the revolver definitely looks to have some wear and patina on it. Off the cuff I'd say if the timing is good and function is 100% it's worth about $300 as a shooter. If the timing is off cut that in half.
There is some growing collector interest in these pre-war double actions, but it's pretty much limited to the minty ones.
OTOH if you have one with good timing it can be a VERY fun and classy, accurate shooter. They seem to prefer .38 Special 158 grain soft lead RN bullets, and the ones I've had were sighed in at 20 to 25 yards with that or a very comparable load. They don't tend to do as well with modern high-vel jacketed rounds.
I'd suggest shooting it bullseye style, old school, with a fedora. See?
