8X10 Wide Angle Gold Rim Dagor. item #7544254880.
I have no personal interest in this item. It looks like the fellow selling it may have been using it as a normal for 4X5.
There's also a series V Protar convertible in barrel with a GE light meter, search under protar. When I saw it it was already up to $5.00 for both.
Could be a real sleeper.
