22 inch iron wrench with 3 inch diameter round head with teeth on both sides

[Farnham]

Does anyone know the specific purpose this big iron wrench was made for?
It has been a mystery on antiquers.com for a while.
Sorry, the pictures are not very well lit.


22 inches long iron wrench with 3 inch diameter or circumference
(I'm not sure which, the OP on antiquers.com is vague)
round head with teeth on both sides. Two sets of teeth.




It looks like the number might be 4-18851. Not sure if a patent no or a part number.

Am hoping someone knows this tool or has ideas.
Thanks in advance!
