This is a retractable pen with a lead holder hidden inside. (The lead holder is broken, pushed inside it's tube)
I am considering having it repaired, but before doing so, would love to know who made it and when.
It's been in the family for as long as I can remember (which in this case is far too long) And has now been passed to me. I'd dearly like to see it back in full working condition since the rest of the pen is in great condition.
Can anyone shed any light on this?
