Mine looks exactly as yours in design so i think they are both made by Komine.
The only difference is the color of the mounting ring and that could perhaps be that mine is a little older in production line or a replacement part? (my serial is H25853)
Another difference is the ring controlling the aperture blades, similar to russian designed Helios and Jupiter there is one ring controlling the min and max aperture and a ring that opens and closes the aperture blades between wide and chosen stop down. Mine says just C----O and yours has numbers high to low.
Do you also have 15 ap blades?
This is how mine looks like, the photo is taken from the mflens forum but mine looks identical in every detail.
