Dallmeyer 2B help

Can anyone help identify this Dallmeyer lens/what its worth? I have no clue so any help is appreciated

Hey Langley! Congrats, it's a beautiful find. You identified the Dallmeyer 2B marking on the barrel. Those lenses typically go between 700 on the low end (think scratches, slight separation of the elements) to 1500+ on the high end (or even more for museum/collector level items).

Your copy is a later version of the lens, with a built in aperture. It's hard to give you an estimate without getting more detailed pictures of the front and back elements, I hope this gives you a place to start!

It's amazing how prices has jumped up in just a few years. I remember being able to find these readily available at very low prices as compared to now.
