Lots of Mis-information here. The COE's like this were production models in 36--and the longnose versions -at least started appearing in 35. They were exported to GM factory in Belgum as chevy bulldogs--and I think to Australia and elsewhere as oldsmobiles. The right frame rail should have a chassis # stamped just behind the front leaf spring. The dash is 39 up style, and I think it has a 248 GMC motor. the book GM the first 100 years has pictures of a 36 longnose and coe with this cab.
