This one’s a bit of a mystery! There’s the initials “RC” and what’s possibly a date of 10-11 scratched into the porcelain on the back of the tank, but that’s it for identifying marks. The porcelain of this tank is fairly rough/crude, so it could be an early tank. The rear edges of the lid have a chip on each side, but are fairly well hidden when lid is on tank. There are quite a few factory runs and voids in the glaze. This tank measures 21 1/2″ wide by 17″ tall, and will extend into the room 8 3/8″. Centerline of the tank’s outlet is 4 3/4″, and this tank is extremely heavy. This will be supplied in your choice of three finish colors.
