.....just throw on an old Kodak Series V metal hood and this lens takes on a whole other look

I have an old Kodak Series VI hood with a push on 42mm adaptor which basically fits all of my lenses... any Canon with 40mm threads, Jupiter 8, Rigid 50 Summicron, Nikkor, Sonnars, just an jack of all trades hood.
I need to find one of those hoods. Never thought of that hood working for a multitude of lenses. I now have a Canon 100 f3.5 from dexdog in the recent and continuing give away threads, that takes a 40mm filter, a J8 too.
I use the same set-up. The lens hood makes the ugliness of the I-50 a "80"on the ugliness scale [out of 100]. Without the lens hood, it has an ugliness score of 95.
