Just a nicely shaped old wooden foundry bottle mold with a nice patina. The half-bottle form is attached to its original mount, with the letter and numbers I assume referring to the bottle type (and there are more handwritten notations on the back side.) A loop at some point was added at the top for easy hanging. Great in the kitchen--or in the wine cellar should one be so lucky as to have one!
Very good vintage condition, with just the right amount of wear. 11 x 4 5/8” x 2 1/4” d.
