The Nishiki Regal frame looked to have close to zero use. The rims were barely touched, knobbies still on the tires... what a find!
But... the seat post was beyond stuck. I suspect it had done some sort of chemical bond. No amount of bashing, twisting, or careful cutting would free it.
I finally tried pounding a squared-off long chisel made out of a broken fencing foil down the cut that had been made, but to no avail. I ended up punching a hole in the seat tube instead of neatly slicing out the seat post.
Fortunately, it was not a priceless handmade bike, so I stripped as much off as I could and snagged a donor Sekine frame (in my size!) that is now being built up with some of the Nishiki parts and some of its original. It has a Dura-Ace brake lever! Probably from around 1974.
