Kittinger Claw Foot Executive Desk

[Aaustin]

Hello! I am new to this forum, so please forgive me if this is not an appropriate place for my question. I was fortunate enough to take in a kittinger desk a few years back. It has seen better days, but not in awful shape. I started to take the pulls off in effort to clean and polish, but stopped myself before making any harmful errors to this beauty. I have no idea the age of this desk or what something like this is even worth? I struggled back and forth keeping it or giving it away. I wouldn’t mind trying to sell it if it is worth anything. I live in Michigan and don’t even know if there’s a market for this furniture or where to go to sell it. So I’m turning to you all in hopes there is somebody more knowledgeable about this furniture! I’m posting some pictures below. It’s very large and incredibly heavy. Thanks in advance for any help/info you can provide!
