ok cool i don't have to buy a dehumidifier . Auckland's climate is constant humidity, it doesn't fluctuate much and the air is never dry (working outdoors in/ around Queenstown & Glenorchy (southern alps) where it does swing, made me realize this). I'll keep it in the center of the room where it is and hope for the best. There is one afternoon sun window behind it, which i'll cover. Aside from that it's got a white sheet covering it.

It's interesting what climate/ time alone can do to something. I suspect my Ken Evans had been barely ridden when i got it, as the 6400 group still had the clear stickers on the parts and the braking surfaces were barely worn, but old mother time and being moved around for 20 years had done a total number on it with many bits of rust on the frame and everything in dire need of a service.
