Thoughts on this object? I think it's two halves of a mould for a toy 24 pdr cannon. For reason unknown they were welded together. If they each were pressed into the sand, then the two halves would have to be welded together later. Your thoughts?

Not sure of the thickness, but perhaps it was repurposed into an anvil of sorts…or perhaps little Johnny and his friends shot their cannons at the neighbors one too many times and dad said “there will be no more cannons made!”
 
No scale to judge by. How large are the molds.?
I’m also curious as to how one would make a core to create a bore. Of course that could be drilled out later.
If I owned it I’d be tempted to try using it. I’ve a large supply of cartridges cases that would be a source for brass.
 
There's a fiver in the pic. A US bill is 6in long, so the form is 5 1/2 - 6" wide and about 12 - 14" long. so I'd say the cannon would be about 4" across the trunnions and about a foot long, this is just a guesstimate based on the bill.
 
I thought the mold was about 5" across and 1" long. I can go back to take measurements. I sent the images to a worker at the NMLRA and asked her to send it to Dr. Terry Leeper (emritus) of WKU as he was their foundry/casting boss who taught sandcasting there.
 
Here's the response I received.

Overall this looks like a cannon casting pattern. Can’t tell if I am looking at an I beam or two pieces of matched channel iron with 1/2 a cannon pattern on each channel. The 4 holes in the iron piece is for locator pins to keep it properly alligned. Cannons have to be cast in the vertical format to avoid shrinkage issues along the surface of the cannon.

You make a sand mould by Cope and Drag. That form would work quite well. Two boxes the same size, half pressed in each, align the two and pour. The holes are for alignment pins so the box forms don't move.

Forgive me if this is a stupid question, but both halves seem identical. Why would we need two?
 
Found out that the same historical society has a finial mould too. Must have been a foundry in town (now village b/c its very diminised from its peak of 5k) at some point.
 
I think they are together so that when the 2 sides of the sand mould come together they line up. I'm looking at those holes in the mould thinking they would be perfect for alignment pins to hold the 2 sides together in the right place.
