Yep, you are right. It's been awhile since I dealt with a ton. ;-)Not to split hairs, but isn't a ton 2,000 lbs?
That is exquisite. It’d be a great piece of furniture just all by itself.
I have not yet seen any closet of such a design concerning the dividers. Are they 50mm apart?
One could design some swinging stoppers to be fastened between the dividers, to stop the slides from falling over, the same time forming compartments and enabling to flip-over slides for searching.

I would be hesistant to use a wood cabinet...
"Storage Systems and Enclosures
"Proper storage furniture and enclosures for photographic materials are important preventive measures that protect items from physical damage, stabilize delicate or fragile materials, and provide basic care for all materials in the collection. Storage cabinetry and enclosures must be chosen and used carefully, however, so that they do not contribute to the deterioration of collection materials. A number of factors influence storage decisions – condition of the photographs in question, frequency of use, space, environmental conditions, and staff and financial resources available. Often only incremental improvements can be made when working with large collections – but these can have a dramatic impact over the long term.
"Photographic materials can be seriously damaged if stored in cabinets made of inferior materials that offgas harmful chemicals or that do not provide adequate physical protection. Damage is also caused when photographs are stored loosely in oversized containers or too tightly in overstuffed drawers. Prints stored loosely in a file drawer will slump and curl, for example, and be vulnerable to damage each time the drawer is opened and items are handled. Glass plate negatives are especially fragile and will break when crowded into file cabinets unprotected or stacked on top of one another.
"Storage furniture, including cabinets and shelves, should be made of non-combustible, non-corrosive materials such as stainless steel, anodized aluminum, or steel with a powder-coated finish. Shelves made of wood and wood by-products should generally be avoided since they contain lignin, peroxides, and oils that can offgas or migrate to photographic materials. New baked enamel shelving units may offgas harmful chemicals since the paint is very difficult to properly cure during manufacture.
"Prints, negatives, and slides can be damaged by enclosures that are poorly designed or are made of inferior materials. Acidic chemical agents from poor quality materials can migrate to photographs and destroy the images they were meant to protect. Poorly designed enclosures can produce the same result."

By the way - just out of curiosity - wich type of wood would you recomand for storage photographic stuff? Is there any preference - with lower RISC.
Out of general concerns it should be a species of wood wich a minimum of resin ! In addition it should be not fresh.....so just the material you need from wood, would be much much expensive..
with regards
As you said, these are decades old warnings, though have the alleged destructive effects substantiated in tests over those years?
No specific type of wood ever mentioned, only the guilty 'lignin' content found in some wood. My earlier post stated clearly, " contain lignin, peroxides, and oils that can offgas or migrate to photographic materials". This has been mentioned for decades, BTW. In more recent times it is forgotten because of the fact that organic dyes used in film or prints fell out of use with digital imaging.
The article https://www.loc.gov/preservation/care/photolea.html was revised in 2002, and is in the Library of Congress.
I do not have the necessary expertise to know if 50 year old wood is 'safe enough', but then again wood harvested in 2002 is still pretty new
