RAF in India WW2

[Benn2509]

I've just found out that my Grandfather was in the RAF during WW2, stationed in india, as a Radio operator/gunner on Wellington bombers.
I'm now trying to find out what squadron he might have been with, missions flew etc.
He joined in 1943 and left by 1946, does anyone have information on this, or more interestingly, does anyone have relatives who might have served there at the same time.
My grandfathers name was Arthur Westwood, and he lived in Manchester, (Chadderton).
I look forward to any replies.
Regards, Benn.
