Dallmeyer No.5 WA Landscape 15" Flange Mount Size?

[Journeyman28762]

I'm awaiting on the arrival of a 1873 JH DALLMEYER NO. 5 WA LANDSCAPE 15" BRASS LENS W APERTURE ASSY that is missing the flange mount.

Does anyone know the size of this mount?

Thanks in advance...

it might help if you measure the diameter of the (threaded) mount, and - with help of a thread gauge - measure the thread pitch (I've answered this on your same question in LF forum)

Thanks, Ron. I'm still waiting for the lens to arrive, but have ordered a thread gauge in the meantime. Just hoping someone here might also have that lens or know the dimensions.
