We went there on one of our Devon soirées. They used to have a beaten up M4A4 Sherman at the side of the car park.
The museum itself is a rambling mess of bits and pieces. From memory, there was a scout car in there, plus lots of artillery. The Mrs liked all the individual stories linked to the exhibits. Probably the military museum she's enjoyed the most
I'll see if she fancies a revisit.
I live in the South, and it's still 175 miles from me
