Just seen this on ebay
CICERO Metal Lathe Cutting setting tools assorted sizes

**LINK**?

Well it's not a metal cutting tool it's a hot metal type line mould. Cicero is the size of the font not a maker. The block is the slug mould and would have brass letter moulds on one side and the flat plate fits on the other side and lets the liquid metal in through the narrow slot, then is slid across cutting off the excess metal and allowing the piece on the far left of the picture to be used to push the slug out.
The brass letter moulds were cut into long brass rods each of a different length so after use could be sorted by their length. The whole set up was part of a bigger machine.

So the question is has anyone seen this before? Any old printers out there?
I have a few of these from my uncle but he had already sold the machine and the brass moulds were stolen a few days after he died. I've always wondered what the rest of the machine looked like.
