System 3R EDM Magnetic Indexing Head w/ Magnet Controller

Description

System 3R EDM Magnetic Indexing Head with fine adjustment screws, and Magnet Controller 3R-7.02.
Chuck and controller were tested and chuck magnet works.
I could not figure out how to index the head with the fine adjustment screws.
Chuck controller does not turn the chuck on, but it does seem to be demagnetizing (chuck magnet was tested with working controller from another unit).
All used items are being sold as-is.
I do not have the ability to test these items beyond what is described above, but I will photograph and describe any problems, issues, or damage to the best of my ability.
Let me know if you have any questions, and I will do my best to answer them.
I am in the process of listing a large amount of System 3R tooling for both wire and conventional / sinker EDM, so check back frequently!
