No. 4 Panoram 103 rollfilm, format 3 1/2 by 12" Manf. 1899 - 1924
3A film is 3-5/8 in width and was made until about 1970, 3 1/4'' net image width
The Panorams may/probably used paper backing specific to the frame length. IIRC 4 exposure and 6 or 8 exp rolls were sold.
BTW I have a 4A but (I surmise) when that film was discontinued [per above] the owner installed pieces of wood to allow 122 film, I assume that for standard 3A cameras, to be used. i've tried sheetfilm stock cut to the correct width but it is too stiff to use on spools without staying close to the darkroom.

Where can I find Exeter paper? I have been saving 120 backing paper toward an attempt to glue them on a bias to make wider strips and distribute the lap, but that is a grasping-at-straws thing.
I have also thought about a slitter to no good end- My best shot is to rig a razor blade(s) and attempt to pull the film thru it/them. Again, I just gotta get huevos to overcome the fear-of-frustration factor

why? agfa has newest avicolor film from 100 to 800 asa/70mm perforated and unperforated. arent there kodak unperforated film. fuji?Nick Zentena said:If you have a spool and backing paper then you can roll your own 116/616 using 70mm unperforated. Film choice isn't that great today but J&C had/has Efke in B&W.
The number used to indicate negative size, and thus film, before Kodak started numbering films.
1 =120
The Brownie's, Bullseyes, Kodets, and Cartridge Kodaks follow different numbering schemes.

xkaes on ebay had and make slitters in almost every size and configurations. one cut, multiple cuts.Dead Link Removed
If you drop in over at nelsonfoto.com and search for "Spartus Full-Vue" you'll see a slitter setup that was made to convert 120 to 127; something similar could be fabricated for cutting larger film -- and yes, it's pretty close to pulling the film through a slot with razor blades at the correct position. Also, look around for designs for "film slitters" for making 16 mm or Minox film from 120 or 35 mm -- there are a lot of them out there, and what works for them will work for you. There was also a posting there with a direct source for the correct Exeter paper product to make backing, and I gave some basic information on how you'd go about fabricating spools if you have one to copy or only dimensions.
I'd suggest getting some blades for rotary cutters (from an office supply store) and a plastic rolling pin (from a kitchen store) -- pull the film from spool to spool over the rolling pin with pressure on a bar holding the rolling blades, and you'll get clean cuts without scratching the film, and there won't be so much drag you'll give yourself blisters operating the cutter. Build this into a light tight box, and you won't even have to stand in the dark while you crank the handle...
Do a *really* good job with this, and you could actually make some money selling "reloads" for various formats, backing and paper for folks to roll onto their own spools. Film for Classics used to get $30/roll for 122 and 124, with spools -- I bet you could get $15/roll for reloads; if you get into fabricating spools, you'd sell them separately, which would help sell film (by keeping costs down, and by making spools available for cameras that don't have two).
And don't think I haven't thought about doing exactly this -- it'd cost a few hundred bucks to start up, though, and I don't have the money; nor do I think I could handle big rolls of film in my bathroom/darkroom that's got enough light leakage I can see a rough outline of my hand after only a couple minutes...
