PGW97 along with two other non-PRV GGs were located at the 'Cornwall at War' Museum, RAF Davidstow Moor, Cornwall for a number of years. They weren't actually on display by the museum but rather just stored there by their owner. They were then moved to Par, Cornwall (near the Eden Project) where, as of writing, they remain. They are sadly still outside, although covered up and in very poor condition.
Whilst PGW97 doesn't appear to be in a good state, it does possess the best of the PRV coachbuilders craft and was built to last so hopefully could be renovated to its former glory.
