This image inside the 'Tramways' Lewes Road, Brighton garage caught my eye. I've lost count of the number of times the No49 route from Moulsecoomb changed over buses in the garage during my childhood when these types of buses ruled the roost.
LUF131F a Leyland PD3/4 of 1966 vintage heads a line of similar vehicles.
