Welcome to the forum. Actually, that is a .32 Double Action rather than .38. The cylinder is too short for the larger round. This is the fourth model in the .32 DA line. The fourth model guns were made from 1883 to 1909, with serial numbers ranging from about 43000 to about 280000.
As DWalt suggested, value will not be high. Nevertheless, if it is in sound operating condition, it could be a fine old shooter to celebrate the guns of decades gone by. Value is probably in the $200-250 range for people with a taste for older S&Ws, but collectors would probably pass this one by in search of one that was closer to original condition.
This gun chambers the .32 S&W round, not .32 Long. I think you may have .32 Long cases in the cylinder now.
ADDED: I see Alan got there before I did. That happens a lot.
