Hi Argus, no need to remove the pitch from the overwind.
Unsolder the leads from the 6 tags at the base of the former, some gentle heat and the core complete with pri will slide out.

Turns data was posted on the forum some time ago, but note that there are 2, tapped windings and their relative positions are important (self/ mutual cap) to the tuning and correct operation of the transformer.

I have also seen transformers that were wound in the "opposite" direction (all windings so it did not matter), presumably from different suppliers.
