I've seen lots of Devil Shakes in a can. I think they are tough but not super rare as I've seen a few over the years in a can. not sure of the bottle prices but the cans seem to get more then the same thing in a bottle usually. Leon.
Looks familiar, I've seen them before. as for the big jug with no name or markings I've seen similar Jugs with varying prices ranging from $15-$60 about.
No Glass maker, nothing on bottom. lower heel in back is some very very very small slight lumps about impossible to make out but almost look like 11 4 3 or 1? 4 3 but way too small to decipher for sure. Leon.
