Ref. : 5110
Production Date : Mid 1960’s
Produced during the 1960’s this small device can be fitted on the body of a Variant pen an act as a magnifying glass. It is made of plastic and got no screw thread, you just pull the barrel inside. The zoom factor is not indicated but I’ve picture the magnifying glass in action. It’s not very easy to capture but I think you can have a good idea of how this stuff works. I estimate the zoom factor around x3, x4. I have not tested this device for a long time and I can says that it works pretty well but the pen became a bit unsteady which can be a disadvantage if you used it for a long period.
