Dear All,

I've a set of Chinese studio flashes which bayonet looks like to be a S-Type (like Bowens, Lastolite, Interfit, ...).
I want to order locally other softboxes but, before this, I'd like to be sure my flashes are really S-Type.

Does someone know where to find the technical layout of the S-Type bayonet ?
I wasn't successful in Googling ...

Thanks and best regards,
Claudio Bonavolta
