The “S” is actually a K on top of a D, which is the emblem for the Japanese toy company Kawada. Dia Blocks are still made and available in Japan today.</p>

Answers.Body: <p>I have solved the mystery. After searching up many different vintage plastic bricks (I had no idea there were so many), I stumbled upon LOC BLOC, made in the USA in the 1970's by a company called Entex.  I still don't get what the "S" symbol on top of the brick is, but they match completely.</p>

Answers.Text: Not exactly like those, unfortunately.  If they really are from the 1980's (could be the gift was in the 1980's, and the bricks are older) they are past what I was looking at.  I was shocked to find so many kinds of bricks were produced in the 1950's-70's that weren't Lego.  I looked at:  American Plastic Bricks, Playskool Plastic Building Bricks, Educational Building Bricks, Sta-Lox, Auburn Bricks, Betta Builder (UK), Airfix (UK), Block CIty, Playmate (Australia), and Loc Blocs.
