I believe that it is a cab difference. off a recent piece of collected literature it has 3 models. One with a 50" bbc, One with a 72" BBc and a 72" bunk and one with a 80" BBc and a 30" Bunk. I think that the 457 was one with 50" BBC and 72" BBC and the one with the 80" BBC is the 459. Also the engine had something to do with the model. I hope that this helps!

There were two basic models in the 400 series - 457 and 459. It made no difference whether
the truck had a 50", 80" or 86" cab. The difference was in the engine type. All 457 models
had 6 cylinder in-line engines and all 459 models had "V" configuration engines, whether 8
cylinder or 12. The type of rear axle had no effect on the model number, just its suffix.
Examples: N457TL a 6 cylinder Cummins tandem axle tractor - K459T would be a 318 Detroit
single axle tractor. Either of the two examples mentioned could have been built with a
50", 80" or 86" cab. The 86" cab replaced the 80" cab I believe in (about) 1975.

What is a 456 ? The paragraph is from a '63 article and the chart is from Commercial Car Journal Apr '69.

There were no 456's. Only 457's and 459's. Its must be a misprint.

Friend sent me Brockway brochure. Looks like there was 456 offered with smaller engines including a gas.

Wow!, I stand corrected. I never heard of that. Never knew they were offered with gas as well.

Offered and number designated, maybe, but produced who knows. I've never seen one.

I have that early brochure with the 456, however none of my later coe brochures make a mention of it. It would be neet to go back in early coe production figures and see how many, if any at all were produced. Great question! thanks Paul

It would also be interesting to know what that model actually looked like, was it based on the F model mack cab like the 457 and 459, or was it a Brockway design. I recall seeing pictures of an experimental cabover that was supposedly developed before the 400 series, wonder if there is any connection?
