It worked for me.

I think it is probably around an 800 series and they built them through about 1949 or so. I can't find my book on the 40's larger trucks, but it definitely could be a 1948. Its missing the headlight buckets. They were attached down at the bumper.
As for the CDL, it depends on your state. Texas has no provision for CDL exemption for antique trucks. Only farm trucks. If you cross state lines with it, you lose your home state exemptions.
It is a serious matter, because if you are in an accident, and it is found that you should have a CDL, it is the same as no license. CDL requirements are getting more stringent all the time. 2 serious violations in 2 years and your license is revoked. And you must have a current medical card signed by a doctor who is in the national registry.
