For decades (literally) I have been searching for (the perhaps mythical?) adapter #14138 which allows fitting the 280 1:4.8 Telyt to the  Televit grip as depicted in Jim Lagers book "Lenses Vol. II"  on page 218. I cannot find this item anywhere in the world. This has got to be one of the most arcane and impossible to find items in the entire history of Leitz accessories. First of all does anyone know where to find one? Second, does anyone know of a precision machine shop used to dealing with photographic equipment that can make one?

Here are a couple. A precision machinist could make one, but it would not be easy as there are some tapers and radii that Leitz probably set up a special machine and fixturing to make them. I think an even harder adapter to find is the 98311 shown on the right, that allows the use of the 400 telyt on the Focorapid. The number suggest that it was a New York only item.

This product also works with the 400mm f5.0 lens head.  I enjoy this combination very much on the Televit grip.  It works far better than the achromat 400mm f5.6 beast.

14138 is a prime candidate for 3D scanning and 3D printing.  I have a car part that I had planned to get printed.  When the virus restrictions lift, I will add 14138 to the parts that I take to the scanning company to see what the price would be.  Once the file is produced, each new printed part should be very reasonably priced.

Concerning 98311, it is not worth the effort to find one for a user.  Of course collectors want them.  The problem is that the center of gravity of the lens goes outside the center of support in Focorapid bearings.  As a result the focus is not smooth and the combination can't be held in one's palm.

Yes but material for 3D print must be adequate.... it's not as simple as for some filter holders, hoods or similar "un-stressed"  items (I made a 3d print of the focus rig of the Elmarit 28 III) : 14138 is made to couple heavy metal parts, the thread for the lenshead is very finely machined and its 3 receptacles along the diameter do engage with metal pins , and there is also the metal  rotating collar; years ago I measured my one with a caliper and made a CAD model with drawings (they must be somewhere) : wasn't a complex task and had the feeling that ought to be not a though job for a good machine shop.

Luigi, 3D prints can be done in metals such as stainless steel, titanium, aluminum, etc.  I believe 14138 is aluminum.  Do you have an .igs file?  That would save a step and associated cost.  The US is starting to lock down following Europe's lead.  I doubt I could do anything with the file until the virus is under control.

Uh... it was 4 or 5 years ago... I made some 2D DXF files with dimensions (I surveyed also the thread with a gauge), and the STEP of the 3D solid model  (*) : sent them to a LUF member ... won't be easy to find... can try. 

(*) the native model + drawings were  Catia V5 files - the thread wasn't modeled, being for a classic mechanical  workshop... is some ISO std., anyway

And my 14138 isn't even here now... left in my home at  mountains (280 + Televit) which now is off-limit.... 😒

Catia is a suite of CAD and related product software.  I recall its output files being .igs compatible.  (The company that I retired from was a heavy Catia user.)  I would also expect that .dxf is convertible to .igs.  With or without your files, I will take a 14138 to a 3D scanning/printing consultant along with my car restoration part when the lock-down ends.

The ebay item looks to me to be a bargain.  You could pay that much just for a 14138 if you could find one.

I have this adapter which came with a box of assorted Leica bits. I  believe it is part of the Novoflex PIGRIFF-B follow focus system. It has "VISA" printed on it. One side has a standard male M bayonet on it and the other side also a male bayonet for the PIGRIFF- see photo below. If it is of any use to anyone, they are welcome to it for the cost of postage.

PS I have a copy of the Novoflex PIGRIFF system Brochure in my document library so PM me if you would like me to email you a copy.

Wilson, PIGRIFF-B used VISBA for infinity use with Visoflex II/III.  VISA is for the Novolflex bellows that use this adapter system.  VISA can also be used with PIGRIFF-C with correct infinity focus on Visoflex II/III, if PIGRIFF-C is modified by removing some parts in the close-focusing mechanism.  Some tabs forming a cone internally have to be removed to shorten the overall length.  This modification is easy.  Novoflex used to offer a factory modification to PIGRIFF-C for use with VISA on Visoflex II/III.  I don't know how they did it.  Once a PIGRIFF-C is modified it can well be worth the effort, assuming 400mm f6.8 and 640mm f6.8 Telyt lens heads with adapters are found.  The system works very well and is a joy to use.  The only downside is that the close focus is limited; an extension ring is the only option for close focus.

VISA is also fits PIGRIFF-D.  But I don't know if PIGRIFF-D can be modified.  PIGRIFF-D is very rare.  I've been looking for years and have never found one for sale.

For reference the Leica R Novoflex/Leica system is a transitional version between PIGRIFF-C and PIGRIFF-D.  That is, it has some characteristics of PIGRIFF-C and some characteristics of PIGRIFF-D.  The Leica R mount on this system is not removable.
