Lucida/jacobus Desk or wall lamp

Enameled shade.
Can be used as a desk lamp as well as a sconce.
I believe this is a Jacobus lamp without being 100% positive about it.
Many details are exactly like the Jacobus.
The typo used for the Lucida print under the base is the exact same one as used on the Jacobus. (see last Pic.)
