^^^WHS^^^First port of call for seal kits is Jon Goodman jgood21967@aol.com . He's in the USA, but the prices are still good, and he's super helpful.
I'll add that what I'm really buying from Jon Goodman are the instructions. The kit is very good, but the instructions are invaluable. There were seals in my Bronica back that I didn't even know existed.
They were invaluable when I resealed a Ricoh 500 - a camera which has enough light seal to cause a worldwide shortage of black foam.
Thanks Richard for that link (and others, greatly appreciated). Which mm thickness is the one to go for...??
Thanks;
Peter
I have a few acres of it. If anyone wants some, send me a message.
