I just got around to reading all of the vitriol in this thread and it was fun , albeit a bit on the stupid side .
Those of us long in tooth always remember that paint coming off inside a heated chamber is no surprise. If keeping the locomotive almost pristine is a concern ( especially in rare older models ) I suggest that Andrew's solution is the way to go , although I consider it a bit less than elegant . Purchase a roll of painter's blue masking tape and then just wrap the nozzle of the fan with a turn or two. Peel off the scorched tape between uses and you are all set. This looks better than having some nose tissue sticking out on the preparation table.
