3 1960s HLC Top Inlet "Shanks Prison" Enameled Fireclay WCs

Warning, totally filthy and one pan is a Twyford Classic. So this little toilet block is on the outskirts of Ipsw, and has no indication of ever being open to the public, specially after the lack of signage and the front part housing changing rooms making it seem like it's only open during football matches. 9 years since the first attempt and passing by. An event was going on at the Recreation ground, went up to look and finally! It was open. I suspected it was a 1970s building which would very likely have AS "Fireclay" pans with seat pads. But it's one generation earlier than that... Without a doubt some of the most eerie looking WCs rightfully called "Prison" by Shanks but also extremely rare in value. The one other time i've seen floor patches of this size was when I explored RAF Tuddenham and found enormous footprints where the pans were, now I know they were along those lines of being the maker of this. One cubicle in the gents has been replaced by a Twyford Classic. They seriously need cleaning whenever they are opened up & put in use. Flushes are decent except for the last one.
