Hi
Just got an old Lachenal 48b EC up and running . The bellows were mucky on the outside and stiff. They were pretty good on the inside, linen hinges were in excellent condition . I cleaned the leather with lanolin / beeswax Hide Food, and that freed them up beautifully. Airtight and now quite free. They've got quite a suck on them when held against a flat surface!
How often do you folks recommend I redress the leather, to maintain suppleness?
