We don't see too many old trucks here in Central New York. Road salt is pretty brutal on equipment. There is a guy in the Utica area that delivers pool water with a fleet of Kenworth K100E AeroDynes; so we see them from time to time.
I did see an International 9400 (I think) the other day while driving around East Syracuse.
Managed to get a shot of this International 9400, though. According to the driver it's an ex-Wal-Mart tractor that is now hauling carnival rides. Took the photo a couple of years ago at the Oz-stravaganza here in Chittenango.
Aaron, The AMT Logging Trailer is a Western style logging trailer like the ones you show in your photos. It does come with the bunk for the tractor as well as the pintle hitch & the headache rack. Might even come with heavy-duty quarter fneders, but I can't remember. As mentioned before, you will need to extend the rear of the frame, though. This might help some: http://thetimbershop.proboards.com/thread/584/converting-amt-logging-trailer-reach
Nice repair job. Your W900 looks really nice. Yes, Palm Springs, California, is a real place: https://en.wikipedia.org/wiki/Palm_Springs,_California It's a resort community down near Los Angeles & San Bernardino. That's not a Palm Springs phone number, though. There are too many digits in the last section. US phone numbers are 123-4567.
Not all of them. KFS has his own Website, as does Double Take Replicas, AITM, & Auslowe. Rhino lists on eBay. GW Trucks (Gary Wallace) does not. If you want something from Gary, you'll need to email him.
The stenciling really makes the crates. A little flat & a little weathering,and they'll be ready for transport. I recognize many of the symbols that you downloaded, but what's the oval one above the "Vorsicht Nicht Offen"? And the circular ones on the sheets?
Well, the answer is: it depends. Many vocational trucks have spokes, but not all. Spokes were very popular in the Northeast (and still are). Sometimes you'll see a combination on older trucks: disks on the front with spokes on the rear. Many fleets in the 1960s & 70s ran spokes. Spokes are also very popular in Australia. So, like I said, it just sort of depends.
What I find amusing is that 1/25 scale cars (based on metric) are popular in the US, while 1/24 scale cars (based on Imperial units) are popular in Europe. Or at least it seems that way.
