Finished truing the rear wheel, and adjusted front too.
Crankset (52/40T), downtube shifter, derailleurs and rear freewheel 5 speeds, 14-17-21-26-32.
Original freewheel was an 13 to 24 teeth that was disassembled and to provide the core to the big one since that was not screwing right into the hub - it looks like the threading is different.

I did a quick ride (don't have the brakes installed yet) and it shifts ok with the friction levers, but sometimes jumps because of huge teeth difference when trying to go lower.
Going upper moves one by one.

My truing "stand"




Frame, fork, headet + seat post - hunmmm. quite heavy.
