Hi There I am new to this site so hope its the right place to post. I have an old (possibly Gandolfi) 10x12inch camera, image attached. I have recently been using it for some paper negative experiments and enjoying the results a lot. It does have a Thornton-Pickard Shutter which seems to work sometimes, but sometimes I get a big patch of light leak with it so I mostly just use the lens cap. I wanted to know if there is anyone who does repairs on these shutters and if people here might know of a contact? I'm also keen to buy some more plate holders (I have three) but browsing online it seems they are fairly difficult to get hold of. any advice appreciated. thanks, Olivia
