Thank you for viewing! ( .ˬ.)" This is an unassembled set of the single-cylinder oscillating steam engine car from the popular "Otona no Kagaku Magazine" (Adult Science Magazine) No. 7. This is an adult science kit that allows you to build a full-fledged steam engine that moves a piston with the heat of an alcohol lamp. Contents: ・Magazine (Otona no Kagaku Magazine Vol.07) ・Appendix: Single-cylinder oscillating steam engine car (unassembled, unused) ・With outer and inner boxes (slight scratches and minor creases due to storage) Condition: ・Appendix parts are unused and unassembled, and are all sealed within the styrofoam. ・The magazine is also in relatively clean condition. How about it for those who like machines and engines, and those who like science projects? (^-^)
