Tee wrench

This can't be that rare a wrench. Got it at auction today and thought I'll take it home and dust off the mark and see who made it. Well the mark looks like a 31 and Rathbone lists Russell & Co. and Gaar Scott as having made a wrench marked 31 but has no photo or description. Is this tee wrench with three square ends that wrench ?

 ok I missed it. Its a Deere wrench. No mystery here.
