Can't tell for sure, but it looks like a 5400 (134"in.wheelbase) series. Not as many of them around. There were more 5700(158"in. wheelbase)series COE's built, than 5400, or 5100 series. Being a 5 window cab, is another added bonus. What are your plans for it? What type/size tubeless Budd wheels did you use? I've had close to thirty COE's, & best I can remember, only two, or three were 5 window cabs. I've got the only one now, that was full air brakes.
