(crossposted from the insignia section of this forum)

G'day,
I'm looking at buying a british armoured crewman's helmet (liner dated 1952) and it has an insignia on the side that looks like it's been hand painted; unfortunately it was painted over at some point post war, presumably when the 'R' was painted on.

But the reason i'm here is that it almost looks like the 7th armoured division's insignia but i'm not sure so i thought i'd come here to ask. I've also a attached a screenshot of the insignia that i put through a photo editor to make it a bit clearer hopefully (1st photo)
