New one for me... I found a couple of these the other day They are stereotype plates for a old press. The half cylinder was used to print before the use of aluminum plates. These weigh in at #40 The ingots are a tad over #50
I cant imagine have to hump these into position, pull the old ones and hang the new ones. These guys probably looked like Popeye. I got a couple ingots as well, I have never run across ingots like these Thought I would post so others could get a look
