Plus a Vtg repair alignment type writer tool, best little gadget for straightening the key bars

Took awhile to find what this is,

Found one like this from a picture in the

Smithsonian Natural Museum Of American History

Catalog Number 1991.0335.03

If want to look

Found this in a box of old tools

Guessing around 1900-1920s

Or as early as the late Industrial Age

1880-1900
