It seems we rarely have good close-up pictures of Frisco F3B / F7B / F9B units. Here are three F7Bs from my "Enid" negative collection, each in Mandarin orange and white and renumbered. F7B SLSF 125, EMD, renumbered from SLSF 5125 F7B SLSF 132, EMD, renumbered from SLSF 5132 F7B SLSF 135, EMD, renumbered from SLSF 5135 Note they carry no dynamic brake fan. Can you see that Intermountain? Also note the characteristic F7 fabricated side grill and the SLSF applied lifting screen spark arrestors. Also note the front truck on F7B SLSF 125, really the rear truck. It uses the early square wheel bearing housing rather than a Hyatt roller bearing. Ken
