I did some looking on the web, and found a site with some pictures of various Diamond T trucks, and they all look pretty much the same! The one that looks most like it, would be the 1949.
I don't generally take the camera around with me when i'm truck hunting, just because alot of times you're right in the persons yard.. and I feel kinda funny about snapping pictures of other peoples stuff without them knowing what i'm doing.. and most times when I first see the trucks, there isn't anyone at home to ask permission to do so.
At least i'd know how i'd feel if somebody came down my driveway, got out and started snooping around my trucks and snapping pictures.
Usually if I spot a truck, i'll pull in to the drive and knock on the door to see if anyone is home.. if nobody is home, I get back in the car and leave.. altho if the truck of interest can be seen from the driveway, i'll drive slow and gawk!
I'll go out there this weekend and try and catch somebody at home and see if it's for sale and if so, what they're asking. I'll bring the cheapo digital camera and snap off a few quick shots.
