The STIHL 040 N Waterpump is a very rare version of the 040 chainsaw.
There’s basically no information about it online, and only two or three mentions.
First up, this 040 N from Tom Gray’s collection.
Chris Goldman took this picture during his visit to Wayne’s Chainsaw Museum.
And these pictures were shared by Wayne Sutton on the Chainsaw Collectors Forum.
It’s a very usual attachment indeed!
