I never knew to have leaks in these bellows either, until I stuck a light
bulb into the camera, sealed it and investigated the assembly in the
darkroom. My two other cameras are fine (Cambo and Toyo).
I'm not sure about the actual age of this Linhof. I bought it used from
Howard Bond 10 years ago; my guess is about 20 years, but I will check with
Linhof.
The bellows are not made of leather. It is a synthetic material on the
outside and a cloth on the inside. The pinholes are at the bottom of the
folds. The synthetic has worn and the pinholes are from the cloth mesh.
I will attempt to repair them using the liquid latex, Ole suggested:

I called the above company today, and they told me that this material has
used for camera repairs before. It comes in a variety of colors, black
included. They will add black talcum to the shipment. It apparently is a low
viscosity latex and should soak right into the cloth. It's worth a try.
Camera Bellows wants $280 for a replacement and Linhof is asking $480, both
after VAT and shipping. The latex is $15 for 250 ml.
