Swiss thread BB cup ID
Trying to identify the cups if you can not see the thread direction is a leap of faith when you press buy it online. If you can contribute photos, then maybe it will make it easier to find them. That keeps more Motobécanes on the road, and that makes me happy!

I have just scored lucky with these Shimano Swiss thread cups and 600 arabesque chainset. I was pretty sure from the photos, but the doubt was present! Some cups have “G” for gauche meaning left, these did not. They had “CH” (Switzerland) and “L”, er left? Notice the arms have “CH” on them as well.
