WWII USA Airborne motorcycle in Adelaide SAustrali

The first two photos are the actual bike. It is basically complete with new belts, ignition, tyres, leather, cables, US period rifle holster, etc 

The complete bike in third photo is in a museum from the Arnhem battle in Europe from the 101st Airborne. 

I believe this bike was flown into Adelaide to one of very many pilot training airfields for use by US mechanics and any Officers during WWII as it appears to have had very little use off road at all ever.
