I can see enough to make an educated decision, but I don't like seeing new screws. I'm not a Canadian collector, nor an expert on Canadian signs. Here is some input. If the thermometer is as old as that piece of wood appears to be, the font on the words "Sales, Service" looks like a new computerized font and does not match the period. Overall, it also looks odd.
To call this a reproduction(repop),means it's copying the original design.I've never seen an original FORD Thermometer designed like that,so I would call it a Modern day Fantasy item instead.Plus the fact that I have seen 3 of these within the last 6 years,and all were honestly labeled recently made.
