No it was not difficult at all. I probably spent more time extracting the coil than rewinding it.
Rewinding took me maybe 15 minutes.
This is one-layer coil and I happened to have matching gauge wire so there were no problem with fitting the winding. I secured it with fabric glue on top.
I will post the photo later.
As for the direction, no it is not important every time.
For instance the oscillator coil's directions are important as it is part of a feedback and reverse you wires and you got negative feedback in place of positive and no oscillation.
However interstage RF transformers are not sensitive to polarity - you simply feed modulated RF and so what difference does it make what polarityy it is? - None.
In 70 such are antenna coil, 1st detector coil, and 1st and 2nd IF transformers.
I however did observe the direction simply because it is easier to follow the drawing once you have drawn it.
