The ones I saw on eBay were $9.99 each plus $3.50 for shipping. I stand corrected, they were $13.99 each plus free shipping.
E Bay " is where I usually see those too. Seems like $10-15 . My Sheridan did not come with one. Does anyone know when they first started being issued ?
wow they cost that much, I'm glad I still have the original on my 79 blue streak.
