the font is a tell tale way of telling the difference between repo & original however there were different sign companys, different fonts, colors , size, etc. etc. there are many other ways to tell the difference & the colors are a big indicator.....each sign has its own indicators & its all difficult to remember unless you have this type of forum ........compare photos with expert commentary....we do not have this privelage when we are at a swap meet, garage sale, collectors house, when pulling the trigger means getting a good deal & not pulling the trigger means not getting your prize or treasure,,,,,,this seperates the men from the boys It would take an encyclopedia to document all the differences between original & repos of all the diffrent signs , pumps, globes,cans, paper , glass, porcelain, font style, colors, size, etc. etc. etc.
.....................another way to tell the difference between repo & originall would be to invest in a spectrometer & analysis
