I've not noticed any correlation, and that surprised me just a bit. I think some, but not
all, of the early ones, have no marking. I also have a fair number of factory 1899
barrels, finished, and they have no markings on them. Statistically, I don't have
enough 1899's to look seriously at the correlation. Maybe 15 to 20, but that is about
all. And, their serial numbers are not distributed evenly.
My sense is that the caliber roll markings have more to do with what segment of
the market they were trying to attract. We have to remember that the 1899 was
a brand spanking new revolver, and they were trying to develop a market for it.
(They had no idea just how popular, and important this new design was to become.)
For example, they named it Military and Police, thinking that that was going to be
the market place. This is probably why adjustable sights were generally a special
order, at first. Throughout the whole 1899 series of ~21000 revolvers, there were
only 2000 sold to the military: 1000 to the Navy and 1000 to the Army. I suspect
the dual chambering roll marking were done for the marketing effort to the military.
I also think that the general sporting arms market may have been confused by both
the Military & Police name, and of the dual caliber marking. They did continue the
dual chambering marking into the Model of 1902 but as far as is known, there was
only one additional 1000 gun contract to the Navy.
