Dennis F108 WrL City of Chester UFM 379K1975 Chester FS just after Cheshire amalgamation. The rolling siren may have bee replaced by two tones shortly afterwards as I have a photo from 1976 taken near Rossett at a field fire where the siren has gone.

This machine was therefore the only City machine to run with two-tones.
