[Tigers] early shifter knobs (150358810575)

[Tony Somebody]

There is an auction on epay (150358810575) that shows a strange shift knob for $100. I sent a question doubting this shift knob was on Tigers and his reply follows.

"For your FYI, The first 56 Tigers were equipped with Shelby American supplied, Borg Warner T10-B side loader transmission, the true Cobra short shifter, reverse lock-out T-handle and that shift knob that you see. From B9470057 and forward the short handle was use and and the knob was changed." 

Norm or anyone who owns/owned one of the first 56 Tigers able to shed any light on this statement?
