Unusual profile with a long skirt that seems disproportionately too narrow for the dome. Most I have seen are made of the peculiar yellow-green glass I suspect was end-run production as Bushwick. Shop marks from L to R: tiny "01" on the first three, XO, X1 and X1. Note the unusual lettering. Unit on far right has unusually wide-spaced letters for this group. Unit second from left exhibits the sometimes seen "slug" lettering. In this case, it appears the area around the embossing was dug out of the mold surface almost to the depth of the lettering, making it lightly cut into the remaining metal.
