Hello,
I am helping my Brother in Law. He has a WLA Dispatch Harley 1942 . It was left out on the families Farm During WW2.Winton QLD.
It is fully restored.
I spoke to Sandy about buying a new Windshield.
I must apologise I know nothing about Motor Bikes. I said I would help Him.
Any help would be appreciated.
