Not sure who made em, but to me they look like a STAR made piece. Embossed S.F. and green. Has a shallow 1/2" clamshell chip and partnering ghost blemish on the lower WG lip to rear side by the mould line and a small dimple flake out of the base edge to rear side. Mentioned for accuracy are some hairline annealing stress lines over the dome and in various places on skirt. More photos on req. $9 + shipping.
