Two different arm insignia, both of the 5th KDP. They differ in construction form the usual chess cloth backed variety. One, possibly an officers issue?, is worsted on khaki cloth. the other is rather the usual patter woven with a thicker thread. Any evidences of both pattern in other surviving badges? I have seen a far greater variety of construction of the 5 KDP patches, some even worsted in bullion, than in the 3 DSK flashes.... what's your advise, gents?
