For reference: in 1948, the Scout 2-1/4 x 3-1/4 with lens, VF, flash, and one set of film pack magazines was priced at $595, or $7,300 in current dollars. The 4x5 model, similarly configured, ran about $1750, or $22,000 today.
Yikes! That was expensive!
When you consider that back in those days the daily wage was about 1$ per hour, that is definitely not cheap.
When I was going through old magazines, receipts, and processed photo envelopes that my dad had saved, I was struck by how expensive photo equipment and materials have pretty much always been. In the mid-1950s, a roll of Kodacolor 120/620 was $2.00 ($22 today). Add processing $0.75 ($7.50) and prints $0.25 ea, so $3.00 ($30), and you're pushing $60 for a roll. Growing up, my film budget was one roll of 127 B+W per month, and maybe 3 reels of Double-8 Kodachrome a year. I didn't shoot color stills until I was in high school and paying my own way with summer job earnings.
I think the tri-color cameras line up like this, against today's equivalents:
> Curtis Scout 2-14 x 3-1/4 is in the same class as the Nikon Z9 or Canon R3 today
> The 4x5 cameras fall into the Leica S3 category
> The 5x7s are the Phase One cameras today
Add in the film budget, 3 sheets per exposure, and the time and cost involved to make a print, and probably 99% of these, particularly the large format cameras, were used for high-end advertising and publication images, the kind one would have hired a Richard Avedon or Cecil Beaton-level photographer to make.
