Made by S.M. Aikman from N.Y. 
Circa 1860s
They made quite a few models ,with different globe shapes and removable globe models , all using this same frame style .
Lanterns from this company are all very solid made brass.
This lantern is near flawless , only one I've seen with this oversized bail .
The bail connectors are interesting,  they used what looks like burner thumbwheels for the ends.
