Strongbox lock identification Herring or Chubb?

Cant help with who made it, but it's certainly not Chubb.

I thank you for your thoughts on this. I just have no idea as to where to look for an answer.

Do you have any thoughts regarding the "dots" scribed on the three screws? I have been told they may mean that the screws were possibly hand made or lathe cut.
Screw slots appear to have been cut with hacksaw. Bracket screws attaching lock to front of box show off-center slot cuts and uneven thread angle cuts.
Any thought on key?
Thank you again.

The dots are the standard way to mark the position of the screws. There should be also dots next to the screw holes. The same number of dots should be paired. This is the case on your last photo.

Does this say anything about whether screws are hand made, lathe cut. They definitely don't appear machine
made.
Than you for your reply.

It does probably not say anything about the production method. Have seen it on screws from the 1960s.

Believe it to have belonged to American Civil War Union Commanding Officer. Used for personal effects.
At least that old.

I see what you mean about the screws. The long one doesn't even look like it would thread in. With the early 1800 locks I have seen, the cases were not cast, and that is the primary feature that makes me think yours is mid 1800's. Other than that, it could have been an earlier lock.
