Very nice and rare RAAF No.13 Squadron patch.
No. 13 Squadron was based at RAF Chivenor and operated the Vickers Wellington until it was disbanded.

The patch comprises different symbols of bad luck:
- walking under a ladder
- a broken mirror
- lighting three cigarettes from one match
- the date Friday the 13th
They are making reference to the squadron's 'unlucky' number. The squadron motto is 'Fratres Diaboli' ('The Devil's Brothers).

Patch is in excellent condition and a really rare item!!!
