RAF Shoulder Flash

[Biggles]

Morning Chaps,

I'm the new sprog on the block.

I bought this a long while ago and the daft seller told me it was Luftwaffe! I was none the wiser then, but now I believe it is pre-WWII RAF. WWII RAF flashes were a light blue coloured eagle, this is an embroidered gold colour. I believe the NCO's stripes were gold too, at some stage. I hope someone knows what era it's from. It's funny though, I found no pictures of the same patch online whatsoever. Are they rare?

Cheers,
Caleb
