1930s White Enameled High Level Cistern from Walter E Mason of Horwich

Found in a pub, the WC pan is a later Shanks Esco. The urinal cistern also appears to be an early replacement, whilst the urinal is original. Possible manual flush cistern before? The syphon used is a G.W Harrison 'Harriap' Model with a 1 1/4 outlet. No washer on piston.
