Petros, as you have seen, there have been discussions on this site regarding Humberside's pair of Dodge K1113 / Angloco 'RATs'. Strangely there's no trace of this one on DVLA although RAT 323R is shown as untaxed in September 1991. Humberside inherited a pair of ex West Riding Dodge K850 / Jennings RWY 369L (untaxed in January 1987) and UWU 323L (no trace on DVLA).
I believe this was originally based in Hull but cannot be 100% certain of this. Moved to Peakes Lane and then moved to Cleethorpes. Ended its career as C division spare.
