No way to answer witout knowing the maker's name
Prior to 1905 is the best answer I can provide
if the model of 1903, 32 cal. made about 1914 if model 1908, 25 cal. made about 1917
A semi-automatic model 1903 hammerless .32 with that serial number was made in 1919.
The marlin model 336, 32 special was made in 1949. f25689=the letter in front of the number justifies the year.
If your pistol is a Model 1903 32 smokeless rimless (.32 Auto) it would have been made about 1933.
What model?
Depends on which model, and condition.
