Antique Card/Game Table

I bought this for $50 at a thrft store. it is very unique and have not seen anything like it. the top turns and has a hidden compartment and as you turn it you  flip the top open to a full table insted of a half. I did some research and could not find it and then as I examined it I noticed the hinges and researched them which are I believe to be soss hinges which were not made till after 1903. That was dissapointing because I was hoping itt would be from at least from the 1800's like that $400,000 from the Antique roadshow. I still think it is amazing despite the year and relly woud like to know the more about it and the value. If  some one could please email me at [email protected] if you have any more  information I would appreciate it. also there is a paper on the bottom that says the Guardsman refinishing furniture co. which I believe is the company that jusst refinished a long time ago because the paper seems to be very old. there is a stamp on the botton with number 360 and also there is a number 8 stamped by the hinges the dimension full open are 32"x32"x30" and closed at a 1/2 table are 32"x16"x30". I hope this is enough information to have someone help me out. Please also email if you have any questions. Thanks for everyone who tries to help me with this game table.
