Hello, I thought I may ask if anyone could help to identify a model train I have. My grandfather left it to me 23 years ago and I recently took it out of the box to take a look at it. I have searched and found a few similar model trains but am uncertain of the correct one. It is a steam engine locomotive made by Mantua. I remember running it on the attic train set he had upstairs and telling me he bought the train the year my Father was born which was 1956. But am unsure the year it was made. I cannot find any numbers on it anywhere to help to identify it. Any assistance or help would be grateful. Thank you for your time.
