I'm very late to this thread, I know, but:

I also have a Comp TA.
It was $65.99 at Goodwill.
Serial no. 4F0961.
Shimano 600 brakes, crankset, headset, and derailleurs.
Campy Record hubs with 36 hole mavic tubular rims.
Tange Champion No. 2
Silver with purple head tube and purple graphics.
Look pedals, since replaced.
Sakae Custom bar and stem
Bernard Hinault Turbo saddle
it evidently belonged to a GI as it has a Fort Shafter Hawaii
bicycle license sticker on it. How it got to Austin I don't know.
My Surly's serial no. is m0120327
