Diane, thanks for the compliments. Message me if you wish. I last made a cam seven years ago, but since then I've only restored oldies. There are very few folders that you can do an authentic bellows replacement, but the Isolette/Speedex and Record/Viking are two and they are very easy to do. This is because the bellows are held in place by a film gate which is screwed in, rather than rivetted (Voigtlander) or under bent metal tabs (Zeiss).
Nigel, bronze is the new black ... though paisley, tartan and polka dot are not impossible.
Oh, and if anybody really wants to wind me up, just call me "Mr".
