Need to see the right side of the revolver as well, stampings, etc.
A lot of similar top breaks were also made in 38 S&W. Need to be sure of the caliber. There were also a lot of cheap top breaks made by other companies. They were the Saturday Nite Specials of their day. I would expect a S&W to be better made, but none of them was a particularly robust revolver and they all used anemic calibers. They were not meant for any more than occasional use.
As for value, condition is everything, but provenance is better. What do you know about it? Was it owned by anyone noteworthy?
My grandmother gave me one (not a Smith) in 38 special. I bought a box of cartridges for it, and learned that the firing pin would set off a round only about one time in ten. It was very loose as well. That one was best suited for a buyback program.
If you compare yours with the one in post #7, yours has more wear and loss of its nickel plating. It's interest is more historical than practical as the ammo will be expensive to buy and it will not be a particularly accurate shooter (sights, trigger, lockup, etc.) It would need to be checked for tightness of the lockup, function of the trigger, etc. That's difficult to do from a distance.
If you want to get an idea of its value, look for revolvers of that model and condition on GunBroker.
Good luck.
