FFS folks, it’s 35mm! 1.5" wide; very much a Barnack-y 1:1.5 aspect ratio—what other data is needed? Show me any 127 camera with a 3:2 ratio! I’ll buy you dinner at my favourite Malaysian restaurant in Adelaide any time!
Talk about sprocket holes is, sadly, irrelevant—I have never seen a 35mm film holder available for sale which displayed sprockets!
