Glad you thought my help was useful.
For viewing park, it’s run by The Aviation Society. http://www.tasmanchester.com
The only other contact would be through the Trident preservation website who are currently re-assembling G-AWZK there, and a cracking job they’re doing. I think the chap concerned is a regular poster on here.
I think it’s WV838 (sea hawk cockpit owner) who is the man to contact ref: the liverpool option.
I sincerely hope you pull it off!
