This is an antique lamp made by PERKO, who have been making lamps since 1907. This one is probably 1950s era… the “as found condition was our indicator. It definitely saw sea time... judging by the heavy patina. We have restored it to almost original condition… the brass was polished, buffed and then sealed with a clear brass lacquer. We didn’t test it but all the parts are there and it appears fully functional. The lamp’s base is weighted and the gimbals work fine. We believe the globe is original.
