"........
double-clutchin' demon........."

Hey Grumpy, I kinda like that moniker for our good Mr. Roo......but there's a query for ya, how many of us out there remember when you
had to double -clutch to properly drive a vehicle?......hmmmmm?
I'm raising my hand......
O.K. Cliff, another 'stunner in progress' my 160 pound piece of dingo bait! As has already been said, your attention to detail (and your uncanny ability to find ref photos of such ancient vehicles) is simply bar-setting.
I must admit tho', the glossy paint job on the vehicle at this point makes me think of the old lead truck toys I used to play with as a small child.....remember those?
And, if you want "nits", the only one I can find is this; My first impression when I saw the sixth picture down was.......Skateboard.

:-)
Keep up the great work pard',
Tread.
