Thank you Zenith,

I suspected that the value of ft would be in the GHz

I'll take a look in my junk box to see if I've anything close.

My reference says 151-0269-00 = FMT5092 or 41632BD

here are the characteristics:
151-0269-00 - Small signal high speed FMT5092

ft min: 1 GHz @ 5 V/10 mA (Vce/Ic)
hfe: min 30/max 300 @ 10 V/20 mA (Vce/Ic)
Breakdown voltages: Vceo: 15 V, Vcbo: 30 V, Vebo: 4 V
Icbo: 10 nA
Ccb: 1.5 pf
Vce sat: 150 mV/20 mA
Ic max: 80 mA
Case: TO-92
