My Link (also a soprano mouthpiece) should be from the 60's and it has that same table figure (See pic). The baffle is S shaped roll over and ends in a perfectly round throat.If it has a round squeeze throat its basically a modern link.
Oval I believe is EB
Those table marks at first looked like a reface to me but a closer look I think they are machine cut. Additionally supported by the uneven spot on the shank end of the table. The kind of spot a wood planer frequently leaves when thickness planing a board.
