Two different 135mm Optars

[Wayne Crider]

I've two Optars; One gives warm yellow-ish reflections and the other colder blue reflections. I'm wondering if one is a Rodenstock lens, but both lenses are labeled Graflex Optar on the rim. Any ideas.

Is one coated and the other not? Are they different ages?

[Dan Fromm]

What are the serial numbers?

[Wayne Crider]

Both are coated. The blue coated one's serial number is 915158, The yellow one's is G39441. Thanks

[Dan Fromm]

915158 is too low to fit in the Rodenstock scheme of things. The G prefix is Wollensak.

Both Wollys, I think.

Thanks Dan; l look forward to comparing them.
