"Yepper", as Mart often says, .... I think it very well could be a floor model, large horn phonograph ....... but missing several parts. See picture below as
an example of what may have looked like.
You would need to locate an on-line forum that specializes in those "big horn" phonographs and ask their opinion.
Even the parts n' pieces for those "big horns" are highly sought after.
I once purchased a table model without the "horn" and searched far n' wide for like 2 years for the horn but without success. Then 1 day a young fellow that lived about 4 miles from me and which I often bought "junk" from came into my shop with another lad I didn't know.
Long story short, .... that new lad said "I know where there are
2 of those old horns in an old dilapaded building right next to where I like".
One was the "Morning Glory" type like the picture below and the other one was the long "trumpet" type like in the 2nd picture below.
