Came accross this on ebay and thought i'd have a go at restoration. The sac will have to be replaced and i believe the feed is clogged with dried ink, but hoping to get it back into working order. Does anyone have any information on this make as internet searches have thrown up nothing. All it says on the pen is "Bastings Pneumatic" on the cap and "made in Germany" on the barrel.
