SPAAMFAA 2013 Annual Convention and Muster

That is unusual but sharp, If I remember Diamond Reo had a similar looking cab but the grill was different style, I wonder if before Reo became Diamond Reo they produced this cab for a short time (hence not many made) and diamond reo used the same cab but changed a few things, such as the grill style.  

Isn't that just a Modified IH cab?
