A very nice mixture - a parcels 116, GUV and 128. Ian believes that this was L243 or 343 (which may have been 50915 with an unrecorded 128 - 91 or 92). The GUV is one of the blue square conversions, note the gap between "Rail" and "Express Parcels" where "Air" used to be! Taken at Langley in 1976. Ian McDonald.
