Clues [ alleged ]
#1 Found only on some Grant [ only Grants ] tanks from two Indian regiments serving in Burma . One is the 146th .
#2 Obviously a field mod .

Suggested purposes .
Lift attachments for loading and unloading .
Tank wader supports .
My theory , because of the bend inward towards the engine cover , used to attach poles to with a clevis pin for engine work/removal/replacement .
I don't think it's used for lifting the whole tank . It has that inward bend and the hole is to small for anything larger than a clevis pin . Making for an awkward angle for the clevis .
Photos show tanks being loaded and unloaded by passing cables under the tank back up to the crane hook .


Now I'm not saying my theory is correct , I haven't been able to find any answers as to what the hell this is for .
Help wanted !!!
