Magnifier

A friend showed me this magnifier this afternoon, which I believe is a magnifier LOOFV, to be used on a focusing stage. In the same collection I only saw a OORES focusing stage, but I am not sure if it fits on that one.

Does anyone know with which focusing stage the magnifier LOOFV was to be used?

Hello Lex,

first versions of FULDY and OORES use loupes that slide into a half-moon-shaped mounting, later versions use the bayonette your loup shoes (with four wings). Although your loupe is one of the early fat type. The changes may be made around 1933 I think but other my know better. I have the later versions of OORES for two lenses with these mountings and two FULDY and can provide some pictures if needed (had to made them still 😉 )

Here are a few of these "fat"  5x viewers. Used on VEHIG, OORES, PLOOT, focoslide, universal copying device and others.  Early versions were slide-in, first completely round lip, then lip with small flat or D shape, then it seems Leitz decided that it would be more secure to use a bayonet version. The code changed from  LOOFV  to LVFOO.  A similar code changed for the chimney, and right angle viewers, e.g. LOOGI to LKIOO.  The fat viewer had a sliding focus at the bottom, the others at the top. For the LVFOO only, the bottom would rotate when locking or unlocking the bayonet, so a small screw and slot were added as can be seen in the photos, below the logo. The OORES transitioned from slide in to bayonet, as did the FULDY, but I believe the VEHIG was discontinued before the bayonet arrival, and all that I have seen are slide in.  As the early PLOOT's used a screw in magnifier and then moved to the bayonet, I don't believe any of the early slide in viewers can be used with the PLOOT.  The PAMOO replaced the LKIOO (prism vs. mirror) but you could still use it with the VISO I.

When you feel like taking pictures that might be helpful, Romanus.

the early versions had a screw-in-ring to mount the camera body, both with cut-out for long-times-dial

Having some trouble with photos and my computer. Here is another attempt at the photos.

Perhaps there's a problem on my side, but I still can't see the photos, Alan.

Romanus, thanks a lot, your images help me to understand a few things. Like so often with Leitz equipment: once you understand it things seem relatively easy, but it takes some effort to there in the first place.
