Colorado Prison spurs made by GUY but not marked. These are fully overlaid with airplane metal. They have arrow shanks which I was told makes them later in his production. Under the overlay these are nice heavy spurs with wide shanks.
The heel bands are approximately 3/4 inch wide. The shanks are 2 3/4 inches long and have 1 15/16 rowels that have 10 points. The opening of the heel band is 3 3/8 inches.
