the original graphic designers for the Moulton brochures was studio of Banks and Miles, a high profile agency dealing with BT, Royal mail and London Transport. The latter with Johnston, Pick and Gill and Banks+Miles New Johnson gives a hint of the Moulton typeface – Grotesque 216 as someone has said. It has differences from the then-current favourite of Transport and Helvetica – note slanted cut to the top of the lower case ‘t’- breaking the mould in a small way. I have a letter on file from Banks and Miles re the Moulton identity but you will see that some graphics and badging did not carry the exact typeface. Straight top cut ‘t’ is the one to watch for. If John Miles is alive, he may well know the answer.
