They are out there but you have to look around and be patient. Most are in collections and show up on auctions. I had around a dozen at one time with midgets and pints mixed but all got sold but two. I was forced to sell my jars back in 08 when I list my job. Some I'll never get back for being too scarce or rare. I've always looked for the 58 jars and also HAHNE & Co jars which also are "58" only variants.Me & my Buddy just dug a Mason that only had the 58 on it & we thought it was odd. LEON.
