I have an early P75 Nib and Feed assembly that I want to clean.
With my other examples, I am able to gently but firmly push the base of the gold Nib forward and slide it off the Feed (without touching the tines).
There appears to be a friction fit, tongue and groove arrangement that allows the two pieces to slide apart.
This particular example will not budge. I've soaked it in warm and soapy water but they still refuse to separate.
Is there a technique, tool or product I should explore?
