John, Yes. All of the Frisco's F-M switchers had the cab roof overhang. This includes the original twelve H-10-44s, SLSF 270-281 (1948-1949), the four subsequent H-12-44s, SLSF 282-285 (1951) and the final unit, SLSF 286, a H-10-44, formerly D&RGW 122, bought from PNC in 1969. They all sounded like big sewing machines! Ken
