Talk about memory lane, when TW was just about over and THHN was the new wire on the block, 1 supply house I knew put all of it's TW wire on sale to get rid of it. My boss (who could never pass up a bargain", bought all the TW that they had. It was about 100 boxes. There were some #14 and #12 ga wire but most was #10 ga and I believe he bought that back in the 80's. I bet he still has some. I had to move those boxes more times than I want to remember.
