I'm not positive who made the ACME jars at first, but I think it may have been Schram because some have been found that have a Drey (Schram) type of glass boss the neck wire fits over. Ball bought Schram out in 1925 and made some of the Acme jars after that.
Quarts list for $3-$5. Try to find a half pint in one of these...they book for $150 and up! []
Hmm...I dont know then. Here is a picture compare to two 1 pint Ideals. It's hard to tell because they are about the same height, but the neckline of the acme is way lower. What do you think? If it is a 1 pint, is it worth anything?
