Never seen one of those before. Pretty cool for an abm mason jar! I have a few larger zinc caps floating around at home I'd give ya if I could find them, but hopefully a few people here are a tad more organized than I!
Salem is 15 minutes from my town. Pretty small population but has always been a big glass maker. Even today Anchor has their set up there. You can still walk around the waterfront and see the big old glass factories from the day. Nice find!
If RB9 is correct it may be a hard find. 2549 sounds like your jar and they say closure as 2541. It's heavily marked with with lettering. It also looks slightly different in the picture to fit you jar. Maybe that's just the drawing.
Its a Red book #2541 Safety-wide mouth- mason, and the correct lid for it will more than likley be more expensive than the jar (25-30 for jar). The lid will be gold laqured with black letters "saniCap Sanitary jar cap" etc. Just my humble opinion
