I have a horn/ siren that was made by Auth Electric Co. Inc. in Long Island City, NY. It is a model 1787 and appears to be in very good condition.
can anyone tell me anything about it- or what it might be worth and where I might sell it?
I also have a horn made by Benjamin Electric Mfg. Co. in Des Plains , ILL. Type SNP.
Looking for the same information
Thank you
