This is a very nice example of the 1084 S. It does not look like it has been used much at all and came with the original box. Unfortunately I think I know why it wasn't used much. There is a stress crack in the tank which might have appeared the first time it was lit. Considering the rarity of this model (this is the third I have heard of) it's not too much of a problem. The crack is hardly visible (can be seen in the middle of the Primus name) and the condition of all the parts is almost perfect.
