I got my old ballpoint working changed the spring to a new spring with a deep flange which wraps around the refill . My choice of refill was the Schmidt Megline P950 M which turns my Parker I. M. Ballpoint into “ a space pen”, that writes in all directions I added some silicone Grease on all the threads with a cotton bud. WOW it all works perfectly “ like soft butter”. The service I got from Mark ( Hand Crafted pens by Mark) was the best , the package was secure with the spring in a small bag and the package arrived before the tracking time . I will recommend Mark to any one in need. P Sharma
