roundball,
You are absolutely 100% correct with the 1-38" & 1-20" twist on the T/C Scout. I found an old T/C Catolog #21 that had it listed as such.
Now I'm wondering if there were older versions that had the 1-48" twist too. I don't have enough older catolog's to check.....maybe it never had the 1-48" twist and it's just in my head?
It's got me scratching my old noggin now
