Oldest bit of kit?

[wheezing donkey]

A couple of HH Lifa vests of '85/'86 origin and one pair of Lifa tights of similar vintage - all a bit "holey" and threadbare but still pressed into service when newer kit is in the wash etc.
My 'piece de resistance' has got to be my '84 Rock & Rum bumbag (de-luxe model with 'no bounce' tension straps), still in perfectly serviceable order, and still in use several times per week. Also an '85/'86 Rock & Run, 28 litre, Ridgerunner GT ( elastic side pockets + zip pockets in the 'wings' of the waist belt ) ruc-sac, now has 'pin holes' in the base but still gets used with a plastic bag liner - the zips on the wing pockets are very stiff.
