Can't shed any new light on Mr. Born, but thought you might be interested that we just bought a 17" square oil painting of windmill scene in an gold gilt frame also with a label on the back saying:
Ramme-Fabrik & Forgylderetablissment
Meget stort Udvalg af
Forgyldte og runde polerede Lister.
Gardinstaenger og runde Portierestaenger
Saavel forgyldte som i alle Traesorter
Rullegardiner og Persienner
