I have a huge lens that is a Gundlach-Manhattan Radar Anastigmat f4.5 with additional markings of 6x8. Can anyone help me with specs? I assume it is for 8x10 or larger it is mounted in barrel with wollensak apeture. Any info would be wonderful. Thanks

It's most likely a 10" lens that just barely covers 8x10.

The Radar is a variation of a Tessar Design. It has a cemented triplet rear element instead of a doublet. Gundlach-Manhattan Co, Rochester, NY, claimed a slightly wider field of 62 degrees vs 60 for a Tessar.

I have one of these lens. Is it truly a 10" lens?
