This thing turned up in a lot some time ago. I looked at it, felt somewhat puzzled and set it aside. Coming back to it today, all I have added to it are a nib I had lying around and a pressure bar. Otherwise it’s as it came to me. I’m not very happy with the section which doesn’t seem right. Apart from that, what is it? The barrel says it’s a Vacumatic but it’s a button filler. The average amateur couldn’t make that conversion. Any thoughts on the matter? Lots of photographs to let you see what it is.
