There are many models of Vacumatics and some may still be unrecorded. If you believe you have such a rare model, please consider getting in touch.
There are also many so-called “frankenpens” — pens assembled from parts of different models. A repairer may have replaced a faulty part with a newer (but not correct) component, or parts may have been mixed at the retailer.
Most Vacumatic models do not have interchangeable parts, but some combinations do exist.
You may wish to return to the previous page and explore another identification path to find the model that most closely resembles your pen.
