Since I bought lot of shanel 5 shutter, the Japanese No.5 shutter, and haven't found detail data. I make a simple summary of this shutter.

 

Shutter models

There are three models 5A, 5B, 5B-S. 5B and 5B-S have aperture while 5A haven't. Difference between 5B and 5B-S remains unknown, maybe on aperture scale.

 

Shutter speed

9 speed shutter, list as 1s 1/2s 1/5s 1/10s 1/20s 1/25s 1/50s 1/100s B.

Additional information

According to my friend who have 100+ shanel5 shutters, most of these shutters are come with wood wet-plate camera and FUJI fujinar lenses (FUJI version tessar). This also showed in pictures above. Shutter mostly screw in origin flange which screwed onto wood lens board. 5A mostly work with fujinar 18cm barrel lens which can fit in it with barrel's aperture.

All these shutters have M type flash joint for traditional bulb flash. Many of them when I got these shutters were sealed by tape to avoid using it mistakenly.
