North Devon??

I bought this jug in a job lot and I wonder if it is North Devon.  It is about 12 ins. high, and 9ins in diameter at its widest point
The Potters mark appears to be scratched into the base.  Has anybody any ideas please.

Lovely slipware jug. It does look 19thC, but there’s a lot of mid to late 20thC French and Spanish farm pottery made in the traditional style, imported into the UK as decorators pieces so I can’t be sure it’s English. Seems to have the number 13 and a mark I’m not familiar with on the base. Maybe try contacting one of the North Devon museums.
