What is this tool?

Came across this tool today while searching for something else . Do not know what it is for or. Hoping someone on this site will recognize it— looks cool!

Not a tool for a Model T  or  A, looks sort of a water pump wrench, but too many other slots, etc., to be for one of those vehicles. I have one each for my T and A Models, and they do not look like this one.

38OVI and Im2bent, you just damaged my perfectly good wild guess, pulled out of a very respectable hat obtained from thin air . . .

Well, now that Major did the heavy lifting, I'm seeing a bottom bracket maintenance tool for an english or french bicycle.  It has a spanner to remove the bottom bracket bearing retainer rings, a crank retainer bolt 'socket' (the square hole), a tapered fork for forcing the cranks off the crankshaft, a serrated fitting for holding the main shaft (which is splined) or chasing the splines to clean them, and a pedal bolt wrench at the top end.  Sometimes splined crankshafts would have opposing flats inboard of the cranks, which might explain the wrench-like fitting at the bottom of the 'fork'.  This tool would have to be supplemented with a hammer, so it is unlikely it was intended for carrying on the bike.

(addendum:  Only the least expensive bicycles use this kind of construction today.  But, this type of crank used to be practically universal.)

Oops!!!  Sorry.  Corrected.   

This is why I never get invited back anywhere!

All the best.

Well, coincidence.  I was hunting for a magnet bar for tools amongst my junque, and in a plastic tool box of box end wrenches I bought 25 years ago at a garage sale I found a multi-tool that is very similar to the ones shown and linked.   I had no idea it was in there.    You'd think the manufacturers might stamp some ID on them, but I guess they save a few cents by not.

I can't put my finger on it. But, it seems that I have seen this spanner before. It falls somewhere in either Machine gun or Bicycle repair category. Definitely vintage with that square nut hole.

As for the lack of markings, for Bicycle, yes it was to save on production cost, tooling up a stamp was costly even then. For machine gun production, it too was to save on production cost, but also to preserve national secrets and prevent against sabotage and factory bombings.

Automotive and Cast Iron stove multi tools were made generally of cast steel aka fluid steel tor forged steel.
