This is a pretty cool koga branded CO2 pump. The canisters are original and unused, seems to be quite a rare thing. Attaches to the bottle cage braze on.
£10 collected from bow (east london) or post at cost
I had a miyata 1200 years ago that actually had 1 braze on bidon bottle hole under the down tube for that device , although I have never before seen one !
