Hi Kerophile, by checking the library and the only other stove using the 4049 (Primus 145) it seems that the 4049 was a bigger 4047, so making a replica 4047 in any case won't give to the stove the original power and aspect. For me is not worthed to buy it from USA, but being a so rare model maybe another collector could be interested anyway, maybe one of those that has a 4049 in its spares Nicola
