It seems like the local collectors are most often the most knowledgeable about the jugs, and the relative rarity of any particular example on the market.
Here is a little information I found on the net about a bottle show in Alabama and hosted by the Alabama Bottle Collectors club. The information also includes a contact e-mail address and a couple of phone numbers which may be worth trying.
