No. Don’t think so . Stamping alone indicates after 1900 or so and Genco was in business from 1916 to around the late 60’s.I purchased a Genco from an estate in Canada. Never been used, came in a sealed box. I estimate it to be around 1845.
So a specific year of 1845 doesn’t quite fit.
I’ve got maybe 20 or so Geneva/Gencos .
