Steve, do you have a link to that Reddit post?
The emblem appears to spell out "JOY"? I also did a search on this and "JY", received no results. The brushed texture appears to be more recent development on later hard rubber and plastic resin instrument bodies. Earlier, they were glossy, or dulled / subdued possibly by gentle bead blasting.
I played oboe for 1 year in my senior year for concert band back in the early 1970's. Don't remember the brand, was an ebonite student model, not wood.
Does the case, if appears to be its original, have any further details that may be helpful for identification? If not, a seasoned woodwind repair technician may be able to identify it.
The most common student oboe on E-Bay is the Linton. They are going for about $500 in overhauled condition, less if repair needed. The no-name's appear to be lower valued.
If it plays decently, may be worth keeping. What are your intents with it?
