19c Mexican 3-D Display font?

This font appears on the back side of certain Mexican revenue stamps from c. 1865. The type could have been made in the US or elsewhere, of course.

Or, like many stamps, the lettering could have been hand-engraved.

Certainly possible. I would still like to see if a source for this font could be located.

It is very close to the Bureau Grotesk, Thanks for the lead.

For the letters themselves (without the dimensional aspect), you can get very close with Bureau Grotesk:
