RJ Corman SD70M #2597 one of the most unique SD70M's on the RJ roaster, this unit has one of the only last remaining Nathan RC5. The RC5 was barely made and all I could find is that there were only about 150 of them made, this unit operates in the Kentucky coal country. The unit still where it's RC5 to this day but is a lot higher pitched now. ( Space, H and F are for the horn )
If you would like to use this horn Lever please give me credit!
