I know they are out of testing, we are not required to have them tested in Norway, and hard to get tested, when i listed everything on Ebay, i did list as untested, but didn't realise that ebay don't allow the sale of markers... How bizarre...!
The tanks where bought in the uk originally, as was everything else... I think i may end up keeping it. I just don't know how to value stuff like this...! I know it all cost me a fortune, and i enjoyed every single mint of use. But for now it is just gathering dust, i moved 4 nearly 5 years ago, and have not used it once...!
