Here is a photo of some of the white police parade dress band equipment. Most is marked either Po or with an ink police stamp.
Your photo of the LSAH band equipment you have was at some distance. Are the individual pieces marked in any way, as to make or date? You wrote that you had never seen an LSAH marked piece of white leather I believe? That is certainly understandable, given the size of the unit. Band equipment would be even more rare. If the equipment is not Po marked, I would consider it LSAH. Here is some more police equipment. Do you have a white LSAH parade drum hanger like my police one?
Joe,
What a wonderful and extremely rare collection of Police Band White. I do not have the White LSAH Parade Drum Hanger. You would have to ransom your first born in order to get one. Joe who is the manufacturer of the White? Is It Kurt S.?
