Here are images of three more fine British molds. The "WD" is for William Davis, one of the founders of the Webley firearms firm. The top image shows two multicavity "gang" molds for round ball...the upper one for 69 caliber and the lower one in 40 caliber. The lower image shows another "WD" marked gang mold...that one for the "No 100" or 36 caliber belted ball. Other "WD" marked molds may be seen here and here.
