Bought a Optimus 111T the other day. Payed aproximatly $25, so it was quite a find. The box is scratched and rusty, but when I opened it up, it looks brand new. Probably unused due to the fact that that the NRV is missing (going to replace the missing part). So what's the dilemma? Well, I bought it to be able to use it, but I'm having doubts. Guess there aren't too many unused stove out there and if I fire it up, there will be one less!? Also the value will probably be reduced. So what should I do? Then there's a question about the windscreen. Looks like someone have been using too much force when closing and it has caused it to crack. Do anyone know where to get a replacement?
