That great picture (and assortment) reminded me that FEDRA, like many makers, was constantly fiddling with model numbers, minor design changes and adding diverse “genres” to their lines to maintain a decent cash flow…
These are examples of private labeling (who the F was Smithian?) and what looks like a joint venture between FEDRA and RENTA-ZEICHNER ( over too many joints..)…
…and the requisite “fat” lead holders (3 mm) + a “glas schriber” ( the brown “finish” was because those models ( and most of their early models across the board) were made of hard rubber…some stinky stuff if you polish them back to black… which is doable
and they messed around with thinner lead as well..the middle three are holders (clutches) for 1.5 mm lead… and a round barrel 2 mm version.. and the ALVIN/FEDRA flat lead “Constructors”
and a few more
Not even geting into their early sliding cam models ( think Haack Sparstift.)
0.5mm Superfines from this era are deceptively hard to find.
They really are!
The more I see cylindrical bodies for 2.00mm leadholders (even better if without a clip, or with a removable one), the more I’m convinced I need a larger sample of specimens with that form factor.
Were round barrels supposed to fit better the needs of stenographers? I read something about this in some blog entries detailing the history of wooden pencils, and many standard pencils for stenographers I own are indeed round — possibly, all of them (from F.C., Staedtler, and a couple of Italian makers). Does this work as well for mechanical pencils?
That is a great picture (and collection)!
No technical info to share, but made me pull out my favorite leadholders…the Alvin 5021S being a particular favorite due to the design choices on these pencils.
. Really love the shorter leadholders for some reason…
That wooden one looks like a Theo Alteneder. It’s quite a beautiful piece regardless. Thank you for sharing.
Yes, that is a Theo Alteneder. It certainly is the flagship of my small leadholder fleet! 
The precise engineering of the grip and clutch, and then the snake wood handle​

Glad you appreciate that one…love to see some pics of any T.A. Collections from the forum.
It’s a rare site for someone to have one or more. There are a couple on here.
That’s sadly true. I only saw them on Leadholder.com over the years, and managed to snag one thanks to @lsd300 only because I was bold enough to ask for one 
I’ll do a search here at some point for examples…thanks!
T A’s and some friends…. (earliest version …1930’s..on bottom …the nose piece evolved into third from bottom…1950’s

Just those 5 pencils is probably $3,000.00
Those Theo Alteneder pieces seem to fly in a league of their own: impeccable style and amazing pieces; I especially love the one with the removable clip: the gripping area and fine tip seem just perfect.
Also, @lsd300 , I may have to ask you about a piece you had listed on the Bay (Alvin P05, very unusual form factor), which I failed to bid on: if still available, I may be interested in discussing it, possibly with some other pieces. Will send a DM.
Ahh…now there’s a collection, thanks @lsd300
There are some real beauties there…. The double ended versions must have been more scarce? Well…I guess all of them are
Wow, how cool! Thanks for that…yep that’s my Theo.
Do you have the date for this? Great reference shot.
(Substantial pointer BTW, dang)
I know that pointer; never tried one, but I consider it the ultimate lead pointer: in my mind, it even beats the different Minfix by Faber-Castell: the design is simply too good. Still, I wonder how easy to find are the spare blades to replace a worn one: I can still find (rarely) some blades for F.C. pointers, but the one for T.A., I assume are next-to-impossible to dig out.

Great, thanks for that.
