Actually 127 film was very popular for a long time, it was one of the earliest formats of roll film.
1912 for 127, so not one of the earliest, 120 1901, 110 1898 (5x4 negatives) and many other formats were introduced that years.
Last year I saw and had an oportunity to buy a Thornton Manufacturing C Tourist 10x8 camera which had a 10x8 roll film back, almost certainly a prototype, would date to 1887/8 before the company became Thornton Pickard. John Thornton was pushed out of the company he'd founed and lived a meagre existence for decades on the Royaties from Patents licenesd by Eastman Koday, film packs and early colour films, etc - an inventor but with no business acumen.
More seriously I'd never buy 220 film and when I worked proffesionally didn't and nor did anyone I knew. I can see the benefits but the local Ilford Proffesional dealer never stocked it on the shelf.
