I think this is real but I would like a second opinion
Here's a pic of the top its not good but it should do, the casting looks like its aligned correctly
also the seller says that the markings on the body look more like C and a A maybe Callenders Abbots Foundry Co Ltd though i do not know if they made no23s.
also no manufacture marks on the base?
can any one tell me which wwi manufacturer used C A markings
thnks xPANZERx
