Hello, I recently was given several items that belonged to my Great Grandmother. Reportedly they were given to her by a very well known and wealthy architecht, when she was his housekeeper. I’m wondering if anyone can help me substantiate if the items are valuable or just decorative? I’m attaching a pic of one piece I found interesting. From what I can tell its a solid brass candlelabra with crystal serving dishes. This thing weighs so much I have to get help picking it up. The markings on the bottom say I.T. 12-17-68. Anyone know anything about this piece?
