Hi and thank you for including me in this forum.
I have recently got my hands on a Primus 1082 300 cp. It has seen some bad weather i think, so the inner casing is totally rusted with the mixing tube stuck to it. I was told by a danish spareparts vendor, that it is not possible to convert this lamp to a 350 or 500 cp, but i think i have seen something in here from an older thread. if it is possible, how much will i need to change with the two?
