Vintage 1930's Selmer Magnitone Saxophone and Clarinet Ligature, WOW

Selmer Magnitone saxophone and clarinet ligature. I've sold around 20 of these ligatures over the years, but this is the first one that actually came with the original pyramid box and paperwork. The box gives the copyright date of 1938, which makes this an 85+ year old item. The ligature functions perfectly and doesn't look like it's been used much in its life. However, the extra external metal piece is missing. This doesn't seem to affect functionality at all.

I invite you to try this ligature risk free. Buyers are welcome to return the ligature for a full refund minus shipping if you don't like it for any reason.
