If it's still in use, I believe they had the SSR fed in from the NATS radar at Lytham St Annes. They didn't have their own interrogator because there is a policy in the UK not to over-interrogate because it causes too much fruiting and garbling, although the St Annes radar had its own little 'quirk' connected with garbling caused by the radar reflecting from a gasometer; gasometer empty - no problems; gasometer full and the reflection would give you a primary blip at about 90 deg on the display from where it should have been.
