Refills for Metal Wipers

Did they look OEM correct? I have been looking for an over the counter correct looking 15" refills for awhile.
I see a lot of 60's-70's period cars at shows and cruise nights with the goofy looking late model wiper blades on their cars. As far as blades this is what I have been buying at Rock Auto. Very correct looking. The 15" blade part number is: 33150
