Hi, I have found your message from 2006 y. about science fair 200-in-one manual. cat no 28-249 I have found just this model in the basement and i like to give it to my children. however it has no manual. I will be grateful if you could send me an electronic copy of your manual. I will be able to send you scans of Marklin (germany) catalogue of Trains 00 and 0 gauge and some model cars from 1938 y. if you wish. Best regards Przemek -- dr hab. med.
