Vintage Kouvalias wood pull duck toy

This is a vintage pull toy intended for a toy collector it isn't for child's play because of the length of the cord. It measures 7" long x 3" tall. Exact age unknown but approx 40 years. The duck and shaft base is wood and the wheels are plastic. The last back wheel is loose but still rolls. All original paint. Originally it would have had an egg on it's back ( like sourced photo taken from the internet) when you pull the toy the egg rolls around it rolls nicely. It does not include the egg. Made in Hong Kong
