Sun 9cm f4

Can anyone give me information about this lens - Front bezel marked Sun Opt, serial # 54121, black anodised body alloy focussing ring - Elmar 90mm copy.

It looks very much like a 100m F4.0 Serenar (Canon) LTM. Maybe the same company?????????.

I had one a couple of years ago and found it to be a fine lens. The attached photo was taken with it..
