Miniature cannon looks old to me

Trying to figure out anything I can about this cannon. It look like a real period piece to me, but I don’t see any markings anywhere

 

@springfld.arsenal ?

 

Size??

 

The barrel is 13 1/2” long

 

Have you put a blanket on that cement floor and turned it over, to see if there's anything on the under side??????? Check under both the barrel and the carriage......(that is if the barrel comes off or is moveable enough!).

 

Cannot see the underneath very well but it is a well cast barrel

How far down the barrel does the bore go? I really don't see a visible touchhole for ignition if it is to be a signal cannon.
