Looks like a Dallmeyer as best I can find.
You mentioned later you thought it was a Dallmeyer. I doubt it. If it
were a "name brand" lens, don't you think the manufacturer's name would
be prominently displayed?
I think this is an old process lens due to the fact it only stops down to
f16--you don't need lots of depth of field when photographing flat art--
and has no shutter. It probably came as a package lens, maybe, part of a
set of lenses, with a process camera. No manufacturer's name is on the
lens since the name was on the camera. I've seen this before with old
process cameras. I doubt the camera maker made the lens. Most likely
contracted it out.
It would help if the lens element configuration and/or image circle were
known. From your photo, it's appears uncoated. So, pre-1950 for sure.
Since the barrel appears factory black finished . . . I'm going to
guess, it's from the 1930s or 40s. It seems too "modern" to be older.
Good luck in your search.

Thanks.
I found later, after posting, that the "TT" serial numbers appear to
be a TTH.

You're right on the age -- looks like WWII era.
