The shutter was worn and the lever that I point with the screwdriver did not catch the tab of the shutter leaf. I bent slightly the tab and added a very tiny amount of lithium grease.

The yellow filter was foggy and impossible to clean on the outer side.

Three tabs hold in place the yellow filter. I wanted to remove the whole lever but it is riveted in place.
The diaphragm is a simple hole in a piece of tin.

The filter removed. I cleaned with vinager and alcohol.

To take the bellows out I nearly destroyed the bellows frame. It took me an hour to reshape it.

My first attempt gas to repait the light leaks with a mixture of white glue, black ink and liquid soap.
I did all the corners.

the mixture has a weird lavender color but it turns black when dry

Nearly dry. It is becoming black.

Ths is the mixture. I used a BIC black pen, some Elmer glue and a couple of liquid soap. I added some water drops too. The mixture works fine, but the bellows were cracking everywhere and at the end I gave up.

In the mean time, I repared the winding knob that was bent.

I decided to investigate a litthe about an easy way of fabricating the bellows. They are sold for 40 € and they are made in USA. That means that the guy who is making the bellows can make one bellows in an hour.

The first thig I did was a cardboard template.

The finished template. I covered the template with tape to protect it.

I draw all the folding lines. I was not accurate enough and that proved to be a real problem.

My first attempt consisted on a layer of thin tissue, a layer of double side tape, paper stripes (I cut the stripes from a map and that little black line is the north-west of Alaska) another layer of double sided tape and a layer of sun screen (a kind of rubbery stuff that is white and blocks completly the light.)

The sun screen glued in place.

The bellows came out nicely but were way to stiff to be usable. On top of that, the whole thing is white!
It took me 5 hours.

Second try: Paper!, but not any kind of paper. It is called RELON and it is used normally to cover books. It is pretty hard, very thin and it blocks very well the light.

With a letter opener and a ruler I marked all the lines and I folded the bellows by hand.

Yeap! the outside imitates black crocodrile! The choices of black RALON paper was Crocodrile, engraved Skulls or a weird art deco design...

It was difficult to fold, but much easier than the last attempt.

It came out nicely. This paper is coated with teflon on the outside and has cotton inside. It is very difficult to tear, very thin and coarse. It took me two hours to make it, so I think that with some more practice I'll be able to make a bellows in an hour.
