I am also too lazy to search this out.:}
Crescent was merged with Davis in either 1929 or 1930 and the guns that were built by them were marked Crescent-Davis. They were sold to Stevens a year or so later and that name was no longer used. The former Crescent-Davis leftovers were marked Stevens.
I think all this is correct and will look it up later and edit if in error.
Therefore, the building of the 3 inch Quail Hammerless had to be before 1929. They are marked Crescent.
Where are the 410 gurus???
Best,
