Google Image Result for http://www.schoolbuscentral.com/gallery/updates/mar05/images/33.jpg International built many busses with air brakes, aut0matics, diesels, etc. This 1970 example has a gas engine so the guage layout is somewhat different but it is evident the shape of the panel and guages are the same. I was involved with a organization that used many of these type busses in the 60's and 70's. The location of the guages and size varys greatly in a lot of International clusters as they could custom build them to suit different needs.
