I found this wrench (no. 1822C) in one of the sheds at work (La Crete Mennonite Heritage Village). I would like to know if this wrench would have come with a case steam engine or another piece of equipment. If it is from a steam engine I would like to build a box so it can be displayed beside our 1902 20hp steam engine.

Seems to be, should be in Rathbone (P81) (At work, looking at auction listing)

Very nice , big beefy wrench :)

(Case eagle on the left end?)

yes from their steam engine kits. i believe its the largest from a set of 4. good luck.
