WW2 RNZAF Cap & Sleeve Badge

A scarce WW2 Royal New Zealand Air Force brass cap badge, sold together with the original owner's RAF engineering apprentice badge. Both are presented in good order but with some rubbing. Interestingly, the apprentice four-bladed prop badge, which is normally sewn onto the tunic sleeve, has had an additional screw mount added, presumably for the convenience of the young airman - Both the back plate and screw are detachable.
