Original 25mm leather air gun piston seal Gamo Baikal Diana New Old Stock

Offered is an original 25mm (.984 inches) leather air gun piston seal. Measures a fraction under 1 inch in diameter and a fraction over a ½ inch deep. Should expand a bit when oiled and screwed down. This is new old stock from when the local distributor closed up shop about 20 years ago. They distributed Gamo, Baikal, and Diana air guns. The box these seals were in is labeled Gamo, but my understanding is that these seals are relatively generic and typically fit multiple makes & models. 25mm was a standard size for many leather piston seals especially for Gamo.
