While at a car show last week, I was approached by a man with a tire gage.
It was made by US Gage in NY, has a rouned face and the fitting coming out at an angle. It said "especially made for Buick" and had a list of the different 1928 Buick series with the tire pressure printed on the dial. I did not have my camera so I don't have a picture, he had the crystal replaced and it was in a leather pouch. He said it worked and it was in good condition. .. he wanted $85 and I have his contact.

I did not have a need and had no idea of its value.......if you are interested I can try and get some pictures.
