Cannon and other peices
 

Hello dose anyone know where there's are from or how old they are. They are quite small. Matchbox size almost. The metal is quite maluble and dosnt magnatise, only a very tiny bit on one of the small rings. On one of the top of the cannon, it had an N on it. And says "H.Models". On one of the other peices it says "2.5 AP". These arn't stamped In, but apeared to be hand carved in.

Looks like a keychain that is quite common in uk castle/battlefield/museum gift shops. Should have one tucked away somewhere myself that I'd have got mid-late 90's.
