Post #182 is fascinating by the distance involved. It does indeed resemble our Pontop/Burnhope Ch5/8 combined type.

The BIII aerial appears to have shorter elements suggesting ch11 Mendlesham. On looking at the IBA VHF coverage map the nearest horizontal transmitters would appear to be Burnhope and Pontop Pike! Mendlesham had 200kW ERP where our Burnhope had 100kW.

Certainly such long distance reception could/would've been possible with the unobstructed sea path though one would've thought more elaborate aerials would've been needed. Tacolneston ch3 was only 45kW, then Pontop Pike was only 17kW which covered remarkably long distances considering.

Cheers,
Brian
