Brio builder construction sets

This is two sets combined. One set is the Builder Motor Set 34591 and it comes with a motor (that takes batteries) and had 121 pieces. Not sure how many pieces the other set had. We may have lost a few pieces but there are still approximately 235 pieces plus hammer, screwdriver, three wrenches, and two pairs of pliers. The motor battery compartment looks slightly corroded (see pictures). All pieces work together so this works as one big set and since you don't build anything specific it does not matter too much if a few pieces are missing. No box. Have instruction material that came with motor set but nothing for other set. Last two pictures are stock photo for motor set and a description of another set.
