These are heads from a low use machine, however its a lot of money.
I am willing to ship these to the Re-Lap guy for an electrical test and lap , you will need to pay about 50 60£ for the Lap and report plus shipping from him to you.
You will pay me for the shipping to him and the head if all is ok
If its duff you will pay nothing at all that way every one is straight and happy
This the record head.
Woelke had a secret way of building these heads which no one ever found out what it was ,as the Woelke heads could erase perfectly with no residue , you will see many different record and play heads but even on the best machines they used Woelke
