Oily,
................. Do you have any kind of a rough time line of the Thorsen ratchets?..............
I'm trying, and I'm being very aggressive with this project! Rough time line, heh? - first came those with plugs, then those open head ratchets with no cover (not chromed), then that little cover over the open-head (and chromed), then the closed head.....with variants, over-lapping production timelines, and exceptions in between and everywhere. With over 40
unique Thorsen USA production ratchets (and the number keeps growing) I'm finding it a challenge. "Free" research material for Thorsen Tool Co. is few, leaving me to personally acquire material and be creative with approach/methods.
I have made progress, but I just don't have a meaningful factual story - YET.
