Vintage 1960s Sta-Lox miniature building bricks toy

This is a toy from the 1960s in its original container with lid. The bricks interlock similar to Lego/megablocks. It seems to have all pieces, including the cardboard roof, which is in great shape. It actually has three more pieces than indicated on the back, so I’m not sure if they included extras or if some of the pieces aren’t the originals/any included pieces have been swapped with originals. The pieces are in great shape though a few are dirty. The container does have a dent in the front, which I tried to show in the photos. No instructions are included - just what is shown in photos. Pickup only. St. Clair West & Spadina Road area.
