DISRAELI DOCUMENTS
In April 1965 Shimano placed this advert for their new parallelogram derailleur the ‘Sportsman’. This is a fairly blatant copy of the Campagnolo Sportman (note the lack of ‘s’). The Shimano Sportsman appears to be very similar to the later Shimano Archery, but has a slightly different pulley cage with a point on the bottom.
Perhaps Shimano had to abandon the Sportsman name because it was too similar to Campagnolo’s model name.
