I have poured through the Wollensak information on Cameraeccentric so most of what i know comes from there, including the various thread mount sizes for the lens cells.

Alphax:
#2 and #3 both have a top speed of 1/100
#4 and #5 both have a top speed of 1/50
Is there anyway to narrow down the identification within the two groups from photos?

Rapax:
#1 and #2 both have a top speed of 1/400
same question; is there any way to narrow down the identification between these two from photos?
side question; is a Graphex shutter the same as a Rapax?

Thank you.
