Wallace Arnold YUG100 was a Leyland Tiger Cub with an unusual Plaxton C37C (later C41C) body. It was exhibited at the 1956 Commercial Motor Show , not entering service with WA until 1957.
By the time of this view it had clearly seen better days, and was only used for contact duties (with notable exception during busy periods).
