This is a lovely tinplate, clockwork liner. Most likely a German manufacture from the 1930's. A lovely, all original example. Has a gyro/clockwork motor, which is in good working condition. 

It measures 22cm in length and is a lovely example. The rear flag is missing and there are areas of light surface rust and age wear in general. Overall the boat has a lovely patina. A lovely old tinplate boat!

For the best idea see the pictures.

From a small, but interesting collection of vintage tinplate toys.
