I always loved the M1 carbine. I currently have three (IBM, Saginaw S'G', and Inland) but have had several others pass through my hands over the years. The only shooting trophy I ever won was with my Saginaw.
Going off of Show of Show prices this year (2023) the majority of the M1 carbines I saw were like yours - assorted parts, pot belly stocks, adjustable sights, etc. and were anywhere from $1200 to $1800, with a few others for higher asking prices. Those tended to be the Winchesters, and those with all correct parts (i.e., flip sights, push button safeties, flat bolts, low wood stocks, etc. )
Likewise, I have a few M4 bayonets in my collection, and while I wasn't chasing any at this year's show, most I saw were in the $150-$200 range.
That said, you've got a nice looking rifle. Hang on to it!
