Anyone know what uniforms these men are wearing? Thanks

I guess they are factory-guards or belonging to the one or the
other Wach- und Schliessgesellschaft.

Thank-you again Wilhelm. Here is a close-up of badges worn by the fellow on the far left. Unfortunately there is no detail in the above two. Was it common to wear a SA Sports Badge on civilian clothing?
