Old huge steel birdcage

20 years ago we were on a mountainside in Worley, Idaho bottle digging. Came across what appeared to be the top of a cage or something. We continued to dig every Saturday for a month straight until we pulled this AWESOME, old bird cage out of the ground!! It stands 70 inches tall from ground to tip top. Cage is 52 inches with 18 inch stand. 30 inch diameter. This cage is huge and built EXTREMELY tough. It isn't ur typical "ornate wrought iron." It is thick, heavy duty iron. No rust. All bars are intact, nothing missing. Original EVERYTHING, even lock on door is original. Cage is in 4 pieces-- stand, bottom piece (with removable tray), middle cage piece and chandelier dome top. Cage can be hung also. The basketball in cage is to show size as with the 33 gallon garbage can I have placed next to it. I have spent HOURS and HOURS online trying to find this exact cage and can't. I want to sell it and was gonna ask $300 for it but was told I was ripping myself off. I really appreciate any info anybody can give me. Thank u much!!
