Default 121mm Super Angulon

I have just got a 121mm S.A. mounted to a Plaubel lens panel.
The lens appears to be fitted into some kind of housing which has larger
rings for the shutter speeds.

However it looks like there is normal Compur shutter mounted into the
housing, yet I cannot remove the lens cells and shutter from the housing.
Normally one has the shutter,you remove both cells to fit into a lens panel.
When you have tightened the locking ring only then you fit the cells of the
lens.
This thing has a flange which screws tothe lens panel by three screws and
the housing screws to that..

I am not familiar with how Plaubel mounts lenses. The use
of a flange for mounting shutters is very common. The use of
a retaining ring on the back of the lens board has become
more common in the last few decades. Some shutters come with
combination rings which can be used as retaining rings if
mounted on the back of the lens board or as a conventional
flange for front mounting. Front mounting is necessary where
the lens board is thick.
Where a retaining ring is used its common for the shutter
to have a pin on the back which fits into a depression in
the lens board to prevent the shutter from turning. This is
almost universal on press cameras like Speed or Crown
Graphics. The retaining ring must be remove from the back in
order to remove the shutter.
Where a flange is used the shutter will unscrew from the
front. However, I've encountered some where the shutter
appears to have been cemented to the flange. Very old Speed
Graphics, with Compur shutters, are this way, but other
cameras are also.
Having said that the lens cells should just unscrew from
the shutter without removing the shutter from the lens
board. I have a couple of Super-Angulons in Compur shutters
and the cells of those just unscrew. However, Schneider was
fond of using tiny set screws on some lenses so I would
examine this lens to see if you can find any.
If that fails, and before using force, I would write to
Schneider giving them as much information as you can about
the lens and ask if there is anything special about it.

What, exactly, does shutter size 0+1 mean?

I have the lens pair for a f8/121mm Super Angulon but no shutter. When I
consult Schneider's literature they specify the shutter size as a "0+1". The
same is listed for the f8 90mm. S.K. Grimes, Inc. quotes an outrageous fee
for installing this lens into the appropriate shutter, so I am left
wondering if this 0+1 thing is so arcane that it justifies Grimes' fees or
whether I can simply remove the elements from the shutter used for the 90
and replace with the 121mm elements.

Does anyone know?

My 1968 Schneider catalog shows the 121 SA fitting a 0 shutter.
Recently 01 was a 1 size shutter with a 0 size lens thread. An example
of this would be the Prontor Professional which came only in 01, 1 and 3
sizes.

Another example would be the current Rollei Linear Motor shutter which
has a 0 shutter size but only fits into 1 size holes for lensboard
mounting.

My latest brochure from Schneider showing the 90mm f8SA as being in a 0
shutter for Copal and Compur and in the 01 for Prontor Professional. If
you are asking about mounting in a 01 it should be the same price as in
a 0 unless your lenses are so old that they are actually 00 thread or
unless they do not have standard 0 threads and require a machined
adapter.

The 121mm S.A. is a curiosity in that it appears in a housing or in the
normal form.
I have seen four examples on ebay, two housed and two normal. One of the
housed examples was also mounted in a Plaubel plate like mine.
My interest in dismantling the lens was in case the thing would fit into the
bellows of a Pacemaker Graphic.
The Primary reason for its acquisition is for my Linhof.

The proper lensboard for a Technika IV, V or Master 4x5 for the 121 in
Compur 0 was the 001017. For the 57 Technika 001051. In Compur Electric
1 the boards were 001128 for 45 and 001129 for 57.
