Bird House Wooden Toy Made in Japan Vintage

I have a vintage pull along wood toy that was made in Japan . It was painted on both sides and says "Bird House". The bird in the front goes up, and down when pulled along. The back part is missing. The wheels pull at times, and sometimes don't. It has a lot of paint loss. It definitely shows wear. It stands 4 3/4 inches tall. The width between the wheels is 2 3/4 inches. The length from the front to back is 6 1/2 inches. I have given a lot of pictures so please check those out. If you have any questions please ask.
