What you have there is the "Home" or as some call it the "Practice" version of the Brown Top TS table. The Brown tops were the last in a series of tables that TS made and yours is somewhere between 1979 and 1981...when TS went under. TS made both the 4X4 leg models and Slant leg models like yours, they are less common though. In fact to the best of my knowledge TS made 7 - 8 different versions/styles of the "Dark" Butcher Block tables....which are my favorite....TS also made a "Singles" style slant leg brown top coin-op table but I am only aware of 2 that exist, the one I have and another in Washington state. Nice looking table!!
