Hi to all,
Has anyone seen this badge before?
I am interested to know if anyone has any information about this badge and the badge mentioned in Thomas/Lord as 37 Battalion being red/blue diamond on black.

The 37 Battalion association pin that was produced post war has the yellow and red colours.

Is the red/blue/black badge an early example and the yellow and red badge a later example. Did they change for some reason during the war?

Any help appreciated.
Thanks
Barry
