I have an early Alecto (basically a Zoraki HP-01). The main seals in the piston gave up the ghost a few months back just before I was about to sell it. Chambers are out of stock and it would appear the original seals are hard to get hold of. Just wondering in anyone else has managed to bring one of these back to life using more conventional o'rings as substitutes? I see Bagnall sell a set of O'rings which they say will replace the original ones.
