Part of the Christmas tree? Just stuffed away in the attic and forgotten.
I inspected a house that had a HUGE, plastic Santa (7’ tall) in the attic. Seems that the owner (3 owners ago) used it for a display, and left it. The next 2 owners never went in the attic.
Once, while crawling an attic, I found an 1862 Civil War Cavalry Sword. I left it there, and asked the buyer if I could do a Pre-closing walk throgh. Then, during the walk through I “found” the sword and asked if I could buy it (after the closing). He gave it to me.
Vintage sword (I collect swords), and assessed at $10,570. I kept it for my collection.
So, I would guess, to the original question, that this is a “vintage” steel beam.
Might be worth something :mrgreen:
