Are you really surprised that I’ve got a few more Füllfixe than usual? I don’t think so.
Hi Martin,
That doesn’t surprise me at all, actually :-)
So 17 m of FP4 was clearly smaller than 54 mm – forget about the film and the gap, so there’s still some leeway.
That matches my recollection. Although the cardboard core inside the film spool was about 10–12 mm in diameter. The cores I’ve come across recently were all over two and a half centimetres.
Best regards,
Franz (by the way, I only have a 30-metre Füllfix made of Bakelite and two more recent AP Bobinquicks)
