Here is a Colt New Service .357 Magnum from my collection shipped in 1941 to the Androscoggin County Sheriff's Office in Maine.





Anyone have an idea who manufactured the sights?

The banded ramp looks like a Pacific Gun Sight Co from the band contour where it meets the bottom of the ramp edge..
I think maybe the ramp itself has been cut back from a longer length (rifle sight) for better use on the revolver.
Their sights were usually all marked with a small 'PACIFIC' stamp though. Not that the marking couldn't have been removed in some carefull profiling or reworking of the sight for it's current purpose.

They made sights & reloading tools from the 20's into the mid 50's. Then dropped the sight mfg biz and continued w/reloading tools.

Most (all?) of the early front ramps were made to fit 'blade' front inserts w/a cross pin holding the blade into the ramp.
Later ones had a dovetail cut IIRC.

Thank you !!
