I am a antique and vintage clothing dealer, and I have recently found an interesting mechanical pencil that I would like to learn more about. I have attached a few pictures of the pencil. I have already learned about the business that is stenciled on the side, and am more interested in the pen itself. Particularly in the small glass tube that I found inside.

The glass bulb looks like a light bulb for a car. My car has two bulbs like this to illuminate the number plate. Considering that this was an ad pen for a car park, it would make sense, right?

I don't know when this pen was made, but should it have been made in the GDR, the bulb might be for a Trabant.

That does make a lot of sense. I will turn my investigation that way. Thank you very much for your insight. If anyone has any other information i would be very grateful.

I forgot to mention that inside the pencil where the tube sits is a spring to hold it in place and on each end is a metal connection. I have to admit though, that I am pretty ignorant of pens and pencils, as I haven't delt with many in my business.

It`s a tester for electric current. Measuring of 6 Volts (old) or 12 Volts (today) in cars would make sense for the pencil being a give-away from the garage, restaurant and repair shop "Goldene Laute". But it needs a cable from the cap top to the other electric pole. After closing the circuit the glass tube is iluminated. The other possibiliy is a 220 Volts AC (alterning current) tester. The graphit mine could be the electric resistance and after touching the cap top two non touching poles in the glass tube begin to glow in a violet or orange color. Do not touch high current! No guarantee that the user afterwards is iluminated in all colors!

Thank you! I very much appreciate your help. I do come across pens, fountian pens, pencils, and the occasional quill (ok, just once), and now I know where to come for helpful insight as to my finds! I will refrain from posting sales or auction listings and advertising my itme for sale, but for the record almost everything I post will be for sale.

      Even so, you'd end up with a fragmented list, and it becomes an O(N²) process for each prospective requestor to check what is available: effectively recreate the list of currently active servers (without any reliable up-to-date info upfront about the inks and number of samples on offer in the thread) from the sequential list of posts, which may be spread over two or even more pages, and then query each server independently to check what is currently on offer.   It comes down to not hav

      If one wanted to do this, one could just use the "About Me" field which appears to be unlimited in size.  And if a bunch of people wanted to cooperate, the Member Title field (or signature) could be used to this end - "Ink Giver" (or some such) could be used by those with inks to give...  No software edits required.

      I suppose the update issue could be mitigated.  One would post a link in signature, to the particular part of your profile where you list the inks that you're willing to post samples to others, gratis.  But looking at profiles, I suspect that would require an edit to the board's software, potentially a nontrivial task.

      I read your idea as getting willing givers to publicly register as members of a set of heterogenous servers, in a system in which a client would explicitly select an available server from a list, to which he/she will then send a request privately and asynchronously. Request handling in the system is unmanaged, and individual requests are handled by the targeted servers completely independently on each other. I think the model is fine, although there are some operational concerns you may want to

      First thought on the method/system of ink sharing: Think the best way, to begin with, is to follow the way of the US thread: offer up a (small) list of inks you are willing to PIF, to whoever expresses interest. Write clearly in the "mission statement" how it works, with a tiny "quid pro quo" that even a struggling student can comply with, i.e. post your opinion and a writing sample, with option of a full review if desired.   So yours truly might say: "I'm offering up samples of D
