Thanks for good and detailed explanation!
I'm too lazy to search web for this. And i don't know what to search also.

Kodak designation.
100 years ago there was rhyme and reason to their number system 1 = roll
film, 20 = gage of film (higher number narrower film e.g. 110 was the
widest 128 the narrowest). Then in the 30's they came out with wood core
spools 616, 620, 828. Since the wood core was thicker than the metal
core the rolls were 6 exposures hence the 6 however by the time they
actually hit the market Kodak was making a thinner film base so they
actually had the same 8 exposures as the 100 series (getting confusing
already). Then they came out with double length rolls of film hence the
2 in 220.
So anyway 135 indicates a metal core (since replace with plastic) single
length roll of 35 gage (35mm motion picture in this case) film in a
cassette magazine for Leica Cameras (they have abandoned the long Leica
specific leader over the years).

I always wondered about this. Being still a film-only user,
I'd like to know what "135" is derived from.
