simplex golf ball marker

This marker once belonged to GHS member John Roth, who passed away several years ago. The vintage metal Simplex marker, c. 1910s, is shown with instructions and in its original box. It’s quite rare to find these items in such good condition. The box may show discoloration and wear but that’s to be expected after so long a time. The item was valued at around $60. Also shown below is an ad for the device.
