Hi Gary. I collect them too. I do have duplicates for sale. I've found them and cleaned them myself. They have different makers marks and different years. I'm not sure what all of the brands are, though. Not all of them are embossed, and they have no labels. Mine are all listed on ebay.
Hi Gary. I like them too. I have found MANY post- 1920s liquor. Surface finds. I didn't have to dig. Mine don't have labels, but they do have the federal law embossed.
