UUUHHHH,,,,,,, I'm not sure,,,, may we see some more pictures from different angles? If Gordon is correct and it doesn't need a lid it may really be something. It will have to have a way to attach to the cage. I'm not saying it's not, I am just wanting to be convinced.
Thank you for the additional pix. Is it too much to ask for clearer, more focused ones?
I'm thinking it requires a lid and is possibly a cosmetic or trinket, covered box. I believe it is a nice item but considerably de-valued due to the lack of a proper lid. Hope someone can solve this for us. At one time my Wife was really into such items, we had a large collection.
Try Googling "Vintage Sandwich Horseshoe Dresser Box". It has the same shape, but just shows the view from the lid. I believe it it some type of trinket/dresser box. Hope this helps. Nice finds.
I don't mean to be arrogant and am saying this in PURE FUN: "See I told you so".[][][] Sorry Gordon! You all please forgive me. It's just that I am fortunate to have had a great deal of experience with such items.
Thanks to newcomer BDBottle for the picture of the lid and a big Welcome to the forum. Hang around for awhile.
