Were not SLSF 1 and SLSF 2 Davenport Locomotive Works, SLSF 3 Whitcomb and SLSF 4 through SLSF 8 General Electric? Charlie
Ooops, I didn't see the "GE." GE 44-ton locomotives were SLSF 4-8. Also AT&N / SLSF 11 was a GE 45-ton. And SLSF 12 was a GE 70-ton. Tom G.
The Okmulgee Northern (ON) Railway company's last locomotive was 1950 GE 70-ton ON 7. It was transferred to Frisco and became SLSF 12. Oklahoma Northern had a Davenport 44-ton ON 8 before getting the 70-ton.
