Hi all.
We've been cleaning out my grandmother's house to put things into storage and came across two lamps that she says are very valuable; for all we know, they could be. She purchased them around the 1950's and somewhere in Ohio. I've looked them over and cannot find a brand, name, symbol, etc. that could let me search for myself, so I'm turning to here in case someone recognizes them. They were originally oil but were retrofitted for electricity at some point.
Included are pictures. The white lamp base is roughly 18" tall and the pink lamp base is roughly 19" tall, from the base to the top of the socket. Both come with the glass chimneys as well. On the dials which I am assuming controlled the oil both says Made in America; on the white lamp it also reads PAT APD. FOR, as far as I can tell. The white lamp's globe was not the original, also, it broke and she had to replace it later on.
Anything anyone can tell us about the lamps would be nice. My grandmother let her house get into a bad state of disrepair while she's been hospitalized, so we've been fixing and cleaning the furniture and haven't gotten to cleaning up the lamps yet.
Thanks!
