What are crank pliers?

Hi guys, I recently inherited my father-in-law's belongings and am assimilating his tools with mine.

One hand tool has me absolutely baffled.

My F-I-L had no link with aviation but, like me, was interested in interesting bits and bobs.

This bod-

-has one similar but his and mine have no crowsfoot mark.

Any ideas guys?

Need better picture of the busness end but appears to be a pop rivit puller as used on Cherry Max aviation rivits. Maybe??

Sorry about the picture

wow, really good guess and it seriously looks that way. Crankshaft might be misleading nomenclature

Says "Crank", not "Crankshaft"
First, is there a hole in the tip to the left, if so, round (size) or rectangular. Could be very early band tightening device (as per tywrap)
Just read caption on website picture. Sounds more like some kind of Brit propeller tool (if the writer had a clue) Looked up the company, now Airborne Systems, parachute/ airborne delivery company in UK. Very interesting! Will dig deeper. I am a retired designer of tools and heavy equipment thus, this one has my mind whirrling.
