A bit of a rarity these: a mint condition ‘bagged’ set of probably the most successful, early ascendeurs. Some of the early die cast alloy ones broke and it was common to reinforce them with tape. Jumaring became a collective term for ascending ropes even if you were using some other device – a bit like calling a a vacuum cleaner a hoover. The climber’s jargon for ‘jumaring’ was ‘jugging’, as holding the handle of a jumar was like holding a jug of ale. Mick Tighe acquired this set from somewhere, but we are not quite sure where!
Jumars seem to have been developed/invented by two Swiss gentlemen called Adolf Jussi and Walter Marti in the 1950s. They used them for climbing up to eagles’ nests.
