World War I or II Photo dating

[hmserge]

I have some old RAF photographs and this one was among them, I was wondering if it could be World War 1 or 11.
I would be very grateful for any information on it.

Thank you

Great thanks, fits in with all my RAF photos from World War II then, I thought the tank looked older though.
Your information is greatly appreciated.

Thank you.

That's not a Sherman of any sort - looks more like a Crusader Cruiser Tank?

Thanks for that, is that still WW2?

[IMBER]

Sorry - yes, WW2.

Crew more likely to be Royal Tank Regiment than RAF.
