CJ - Well, it seems you live opposite to my recent (23rd Oct 21) Son-In-Laws’s Grandad!
I saw your weather vane some months ago and have already drawn designs to make a copy! - having noted the lack of rotors I aim for a ‘representation’ of rotor blades even for my inshore location near NWI.
I was there 1975 to closure and moved to Shawbury til 1980. I believe you speak of M/Plt Alec R*****, who became the UTP for Tern Hill and Shawbury til his retirement (1978 ish).
