That set is merely at the threshold of fully evoking Nostalgia...what with its Pee Cee board and its new generation of redunant type and functions of tube numbers all ...recreated yet again.

Now...Decisions ..decisions...decisions, do you want to start off at A and tie off or else start at either B or C. ???

No problem seeing the cord routing on the large drums with them merely being depicted as heavy black arcs, but your viewed routing around the tuning shafts concentric drum has that drum omitted to better see the exact cord routing, entry ....in front of or behind, cw or ccw, and the turns count...(With my supplied center marked intermediate green arcs, merely indicating that the cord is passing over, and sharing the grooving within a pulley.)

If you are not adept at doing this , pull out your heavy cotton / kite string and do a preliminary stringing to confirm that all cord routing and turns, knob directions (you turn the tuning shaft right, but 'da dial pointer goes left !) are proper when doing a complete end to end travel of the tuning condenser. (WHOOPS.... I only put on a 1/2 turn where it was supposed to be 1 1/2 turns....now I see why that condenser won't turn any further !!)... Then you can measure the cheep trial run stuff and see exactly how much of the hi-dollar stuff + 1 foot... will then be needed to do it again for real.

However, I will now get you started,...first you pull out your big ball of string and unreel
'lebenten yards.....
