No restoration. The pen is in very good condition. The lid and the end cap both unscrew easily. The plunger pushes in very smoothly. No cracks or abrasions. I am not familiar enough with these pens to break the seal and open the main chamber. Cosmetically it is wonderful. The pencil is also cosmetically very good but I cannot get the two halves to click together (photos 9 & 10). I do not know if this requires a major repair or if I'm doing something wrong. Sold as-is, not functioni...ng. The original box is in very good condition other than the small gold panel missing from the front (shown in the photos). Twelve photos posted. Another Vacumatic pen is currently being auctioned, please check my store. FREE SHIPPING with tracking.
