Found this last week while detecting, thought it was modern until the other day I looked at the 6 number Pat date 488760, year 1892 ? It is made of copper. The band is one inch wide, with a slot in it. It measures 3 inchs across, looks like it would fit aroun some type of hose. My pics arent to good, but maybe someones got a clue. Thanks for looking.Oh and the letters and numbers read 11/2-4 W-SHERMAN on the top face of the band with the pat date on bottom.
