Ben,
There are at least 9 more FWD's over here in OZ.
Three have recently gone to the scrappy.
(Two in South Australia and one that I didn't know about only 100km. from me, late last year. )
I have one, (mine is unrestored), and so does Glen Stones at Swan Reach, Vic. Glens is one of the best restored trucks you'll ever see. Bob Dimer in Western Australia has a fifth wheel on his. He drove it on the "Back to the Track" trip from Alice Springs to Darwin in 1995.
The RAAF used them as tippers during WW2and post-war.
(I had noticed that you stated only 2 in the world in your Milweb advert.)
Good luck with the sale. Pity I can't afford it, as it will take me forever to get mine to equal yours.Are you going to let us in on the possible new purchase????
Regards Rick
