Sinar mystery rear standard

[trdrew]

Can anyone help me identify this Sinar rear standard? Photos are attached. This standard does not have the normal tilt function as the regular P rear standards do.
Some have told me this is the rear standard for a Sinar C, but it is my understanding that the Sinar C is comprised of a normal P rear standard and a normal F front standard.

Thanks for any help you can provide.

I think this was the special version they made for portraits, where rear movements would not be needed.

If I remember correctly it was for the Sinar Special Repro cam!

No.
This is definitely in the P series. The F series had two vertical posts instead of the single one in the P designs.

It wasn't on mine for sure...

It's a different 8x10 P standard, not the usual ones you see.

From glennview.com:

"8X10 P/C/F Special Standard bearer , from 1986 Sinar catalog.........."Sinar part number 433.52, Special Standard bearer Sinar P2/C2, Heavy duty bearer for 8X10 coupling frame". This "optimized for 8X10" standard bearer has 100 degrees of swing and 80 degrees of tilt, 70mm rise, 10mm fall, 2 bubble levels and geared focus with depth of field scale."

Except, I don't think that description is entirely correct, because it doesn't have any tilt, does it?

The "special 8x10 bearer" is reinforced and a bit lower than the regular 4x5, but I don't remember any other difference - it may have had more restricted movements, but it doubtlessly had tilt.

The generally advertised purpose for the non-tilting bearer seems to have been for copy cameras. But as the few used ones I've seen were from dealers specializing in government surplus, a more relevant purpose might have been dumbed-down P versions for police mugshots, where movements weren't needed and quick-change slide backs put an extra load on the rear standards.

It's the same as the standard on my C and it does have tilts!

Can't be there are not any knob for tilts or swings they are not needed for copy work!

There are markings for angles on the side of the dovetail. I know that doesn't mean it has tilts but.

[Armin Seeholzer]

The scale is there, because its easier and cheaper then to put a special one there! Without knobs and mechanism there is nothing possible and it just shows fixed, just have an really good look!

It probably can tilt at the base rail joint, as that is nothing they could save weight or cost on - it very obviously cannot do the geared in-plane tilt of a regular P standard.
