Can't tell you much about these oldies. The one on the left has US threads and a glaze that looks like it was filled with fizz as it got fired - pretty crude. A couple flakes off the firing rest are full of soot - I'd say it is probably as nice as the day it was made. The one on the right is Aussie. It is ancient and has but a base bruise to mention for damage. $15 each + postage. How about $8 each or $15 for the pair + shipping
