Thank you for the big compliments Jan and Tommy.

Are you sure your grandparents didn't buy that new and finally gave it you?
A little story about it. I would have been happy if it had been like that. One day my old aunt (my mother's sister) who is now 84 years old visited us. When she saw some of my steam engines, she said that her father, my grandfather, had also owned such a steam engine. Unfortunately, I never met my grandfather Fritz because he lost his life in Stalingrad (Russia) during World War II. So he couldn't leave the steam engine to me either. During or after the war my grandmother sold the little machine. She stood there alone with 3 young daughters and often did not have enough money to buy groceries. The proceeds from the sale of the machine came in handy. The sale of the small steam engine helped to alleviate the hunger of 3 small children.
Best regards
