r/Drafting_Instruments

Hello! These drafting instruments belonged to my grandfather, and I need help identifying them to sell.

The 1st pic are both Keuffel & Esser Paragon. I think the top one is a 6" hair spring divider. The #15 is stamped inside. May be model #402? I can't pin down exactly what the bottom one is. I'm coming up with "bow pen w/needle point," may be model #756?

The 2nd pic is not marked at all, but looks like a bow pen. It appears to be missing a part.

The 3rd pic: this Alteneder pen was in the paper sleeve and it is marked "T.A." and "s.s.". What is the exact name of it? I'm coming up with a few different ones so I wanted to be sure. It's in really beautiful shape, with no rust and no cracks in the wooden handle.

The 4th pic is an unmarked part that was in the box with the other items. Not sure what it is or if it's worth selling.

Everything was in an unmarked wooden box, and I don't have any boxes or sleeves other than for the Alteneder.

Thanks very much for any assistance!

Recently a rash of sellers on Amazon are selling dotting pens. This was kicked off by a Kern one being sold for a ridiculous amount so others want a piece of that action. I have posted a photo of the one I bought compared to an antique richter pen. The Amazon pen has a weak spring and the pen does not remain fixed on the arm as well as being low quality. It’s also giant. This pen does not work so save your money. As a prototype it’s a nice start but as a final product it’s no good.

Ho acquistato un kit flipper usato, ho notato questo autografo sulla scatola dell'espansione WI-FI, Pensavo fosse normale, poi sono andato online per vedere e ho notato che le scatole trovate online non erano autografate, allora guardando bene la mia scatola è proprio fatta col pennarello, non è stampata. qualcuno la riconosce?

Does this nice little compass/divider that I found in a thrift store ring any bells for anyone? It came in a plastic clamshell for a Uchida KD-Type .05 microsharp compass, which is certainly is not. It's quite solid and well constructed, very satisfying to hold. No maker's mark or country of origin. No logos. Nothing stamped or engraved on it at all. Image searches on Google and Ebay find tons of wrong (often spectacularly wrong) matches, but I haven't see one yet with a similar lock/release mechanism. The lobed plate jutting out from the hub has a spring under the wide end, that when compressed with your thumb lifts the other end, which acts as a brake against the hub. Push it down and you can move it freely. Release, and it rigidly holds its position.

I kind of suspect it might actually be a hand/machinist made one-off, but if so, the execution is excellent. Unless somebody recognizes the design, it might even be a prototype or a patent model, but that's just wild speculation based on not much of anything. Any information would be appreciated.

Nice brass compass of the type used in primary school in Ireland in the 60s and beyond?

The first compass is by Kraft & Sohn out of Vienna and dates to the mid 19th. Century.

The second is an unsigned beam compass that dates to around the same time period. This style with the base plate are extremely rare to find. W.F. Stanley wrote about this in his 1866 treatise on drawing instruments, and went to great lengths describing this compass and it's shortcomings in favor of his own design. He was the OG My Pillow Guy.
