Thank you for sharing. (Not that much for the article, but the photograph of those boxes on the shelves.)
To your topic:
Those were the cameras people actually used. Most of those cameras disregarded by many here at Apug are those cameras that actually took those masses of photographs.
And that is why I got a roblem with the term "toy-camera"in general.
And boxes were definitely no toys.
By the way, I hardly ever come across a Brownie over here.
That's why as Rick pointed out above I posted that article on the Antiques forum. It probably could have been on the Medium Format forum.
Because Brownies were made in the UK from the middle of the 20s, we see them very often here. Specifically the ones that take 620 and 127. There are a few models "Made in England" that take 120 rolls.
I have one of these: a Brownie Cresta II. Found it on a charity shop in a nice case and complete with flash, bulbs and the last boxes of film used by the previous owner.
It has a roll of FP4+ now.
