I wonder what you all think of the unusual markings on the back of the flange.

Recycling of a round brass plate from some sort of naval/surveying/astronomical instrument.
I have used all sorts of brass in making the elusive flanges
Wow, that is strange, especially on what would be the inside of the flange against the wood. Perhaps it's like Steven says, just a recycled ring from something else. Very cool though, and I like these early American daguerreotype lenses, as you know.

I think Steven is right. For an optical equipment manufacturer, there would be advantages to using brass castings that would serve on more than one type of optical device--or that could be pressed into service if regular flanges were in short supply one day.

I'll go with Steven on this one too, probably recycled from other use. The only thing I can think of for having such markings on a lens would be measuring rotation for astigmatism, but that's still a wild and pretty unlikely guess...
Is there an engraved marking on the barrel to line up with the degree marks on the flange?

Hi Mark,
No markings on the barrel.
I could buy into the recycle theory except I have a hard time imagining what else this flange could have been previously....

The top of a tripod, transit, telescope mount...to start with the "T"s!

Ah yes.... But it just so happens to align precisely with the flange for a 1/4 plate photo lens ? The markings align perfectly with the flange. I don't see how it's possible. But I'm stubborn.
