Selling as as I do not know who the maker is, it was my mother-in-laws. they were avid collectors. I do not know who the maker of this is it’s supposed to be bronze but kind of looks like copper maybe it’s a mix selling as is I know I have talked to a jeweler and the back he needs a tube and needs to be soldered back, but can’t be repaired and then the glass is cracked and the two spots so so please look at all the photographs that can also be repaired as well and the thermometer is in great shape, but I don’t know much about mercury and it doesn’t look like it’s taking temperature, so more for display again selling as is thanks so much.
