My first job related to photography was in the darkroom of a moderate sized camera store in 1940.
We used, as did many others, total development of film. In other words, the film was developed until it would develop no more. This produced very dense highlights, and adequate density in shadows. The same process was used for all film regardless of maker or speed. They were all developed together. Of course, the norm for that time was to contact print everything. Enlargements were a special order, even for 35 mm. until the special 35 mm automatice enlarger was installed.
Our method was to spend the last hour each day hanging all of the roll film on a large rack and place a 2 oz lead weight on the bottom. This rack was then lowered into the developing tank which was quite large and about 6 feet deep. The film was left so suspended overnight. The next morning the film was moved through the remainder of the processing, dried and printed.
The developer of choice was D-23. I worked in this situation for more than a year and the developer was never changed. The advantage of the system was the silver present in this used developer replated the highlights and brought them up to a density which was appropriate for contact printing.
When I run into extremely flat scenes today, such as Stovepipe Wells Dunes in Death Valley in January when it is not unusual to have 2-3 stop clouds, I still use this method, although I cut the time to about 3 hours. I keep used D-23 for this special purpose.
This method, coupled with a lens from the same era and slow film should produce a similar look.
