☆Sinar S 4x5 Made in Switzerland Sinar S 4x5☆

This is a used Linhof Technika IV 4x5 camera.
(Includes Linhof adapter and 15cm extension rail)
The tilt and shift movements (vertical, horizontal, swing, etc.) are all in good working order. However, there is a slight issue with the fine focus adjustment due to wear on the rack and pinion mechanism at the center of the mount base. The worn section of the rack is only about 1cm in the center, so if you avoid that area, you can still focus using the front and rear rack sections. Furthermore, for larger focus adjustments, you can move the front and rear mounts to achieve focus, so once you get used to it, there are no operational issues (focusing with the pinion gear is still possible, of course).
Regarding rack wear on the Linhof Technika, I've heard that the pinion gears were originally made of a harder metal and the softer rack was designed to wear out to reduce replacement costs.
The rack on this Linhof Technika was replaced with a hard plastic rack, different from the original, at Gin-ichi Camera, but it is also currently worn.
(The rack structure itself is a simple flat structure with linear teeth, so it might be possible to 3D print one now?)
I have not tested it with a pinhole, but the bellows were replaced with new ones once, so I believe they are still usable. Also, as shown in the photos, the spirit level is functional, although it is a bit worn.
Please consider the bag bellows for wide-angle lenses as a bonus. There is a repair mark from adhesive on a scratch about 1cm long, but I believe it can still be used as is. However, if you make a few modifications, such as attaching some moltoprene to the plastic frame, which is still intact, you can use it with more confidence.
