I recently got a Brownie no. 2A camera, which takes 116 film, and I want to have a go at running 120 through it. Three spools came with the camera. They look like 116 spools, all the measurements fit, but they don't have a winding groove that fits the camera. Instead, they have a round hole at one end and a square hole at the other. They are marked "GEVAERT" on the flanges. The camera has a winding knob that fits perfectly to a modern 120 spool, which is too small for the camera. Can anybody identify these spools? All the pictures I've been able to find of 116 spools have winding grooves. The picture shows one of the spools alongside a 120 spool. One of the spools was inside the camera, which is rather odd, since there doesn't appear to be any way the camera could actually wind it.
