Acquired this years ago at a train swamp meet for old train related stuff. He told me it was a central railroad door knob out of a caboose -its porcelain it is as seen. No chips or cracks. But no metal guts either. But i thought it was cool then. And still do. I must downsize my collections now since my age and quantity of stuff. I hope the buyer will save it for the next 6 decades. Things like this are not that easy to find. . See pictures

thank you for looking
