Asking for help for a research
« on: April 21, 2019, 05:30:59 PM »
 Hi all,
since some months I am gathering information (pictures, serial numbers) of Carl Zeiss Jena (GDR), Carl Zeiss Oberkochen (West Germany) monocular models in order to find out whether there was any system of using left-hand sided or right-hand sided binocular housing designs for the monoculars. A question which arises again and again when collectors wonder, whether and why the makers decide to build a monocular according to a left side or right side body of a full binoculars housing.
Main models concerned are 6x30, 8x30, 7x50, 10x50, 15x50 or Oberkochen 8x30B (versions 1, 2, and 3 with objective focusing). Other models may be included, especially predecessors like pre-war 6x30, 8x30, 10x50, rln 6x30.
If you can supply information of your monocular model concerning left or right body design plus the serial number to put them into a chronological production list, I will be thankful.
The first picture shows a right-hand sided body with a left-hand orientated eyepiece/ocular.
 The second picture shows a left-hand sided body with a right-hand orientated eyepiece/ocular.

Hallo Uli,

interessantes Thema. Ich habe mich schon manchmal gefragt, ob man beim Kauf eines Monokulars zwischen rechtsseitig und linksseitig wählen konnte?
Hier meine Monos für deine Liste:
Simpsilv 6x30, Seriennummer 2730032, linksseitiger Körper mit Köcher
Deltrintmo 8x30, Seriennummer 2423358, linksseitiger Körper mit blauer Wildledertasche
Pentekarmo 15x50, Seriennummer 2978787, rechtsseitiger Körper mit Köcher

Gruß Ralf

Hallo Ralf,ja, besten Dank. In den Prospekten gibt es keine derartigen Hinweise, dass ein Kunde wählen konnte, ob man die linke oder rechte Korpusbauform haben wolle. Meine Idee wäre da kurzzeitig, dass es für Leute mit dominatnen rechten Auge günstiger ist/wäre ein rechesseitige Mono zu haben, da es beim Halten in Fergnlas-gleicher Ausrichtung nciht an die Nase stößt. Abr man kann natü+rlci hbei Monos das ganze Isntrument einfach entsprechend drehen.

Meine Vermutung ist eher, dass es Produktionsreiehn gab, während denen das ein oder ander gehäuse verwendet wurde. Geht man von Produktionsriehen von 100 oder mehr aus, müssten sich ggf. anhand der Seriennummern dies annähernd verifizieren lassen, bzw. man könnte Nummernbereiche eingrenzen, in denn es nur die eine doer andere Bauform gab.
Aber das ist gerae noch eher alles Spekulation. Vielleicht gab es auch andere Gründe oder oder ...

Dear Uli,

if I understand correctly from German your post, as I wrote long ago, the hypotheses of the right or left monocular are many.

Valid your hypotheses of the dominant eye, and the possibility of using both left and right tubes already produced for binoculars, but it's possible that was to facilitate hand held for right-handed or left-handed people.

Unfortunately, I haven't never seen in the catalogs in the catalogs a specific offer for left and right monoculars.

Only now I have read you English version of the question  ;)

To my previous post, I add that this feature was already present in the past. I have a monocular prior to 1907 "left" and two DF6x30 mono RLNs, one right and one left, which someone later joined with two metal plates, to make binoculars.

Actually, Rodolfo, one of your posts or questions triggered me to start gathering information for an overview aobut those models with left-hand or right-hand design. I will post my resutls in the binopedia research section as soon as I think I can say more.
