Found this 4.5-inch at a gunshow this weekend, a couple of good-old-boys had it up for sale, they thought it was a 155mm. Fairly well marked with a S.C.C. * 2.12.15 c 4-5 How R. V, it has a No. 100 IIB Fuze. My question is this, what are the peened markings on the body of the projo for? There are four dots on the base, just after the V (12 o'clock in the photo) and three high on the side just before the ogive. The fuze is stamped "reject", could this be a reject marking for the body, or just a weight zone?
