British Army Formation Sign ??

[5thFoot]

Hi we have had a question from an unregistered user:

"I currently own a ww2 1943 Norton War Department motorcycle, I have sent details of the service number etc to the Royal Logistical Corp who responded with no details available.
I am now trying to discover the origin of the 'military crest' painted on the sides of the fuel tank.

Description;
Red shield, Light Blue diagonal stripe up from left to right, White sword vertical with sword tip at top."

It's probably an army formation sign:- swords and shields being common components of a number of these. (see couple of examples below)
thing is there are hundreds of them, army corps, brigades, etc.

I am sure someone will have a text on the subject and be able to ID yours from the description above.
