Although his very first model was Italeri’s 1/35 scale Willy’s Jeep, Mario did build quite a few 1/72 scale Airfix and Matchbox airplanes as a kid. In his teens he switched back to AFVs, mainly of German WW II subjects, which is what he has been building since. For many years now he has been publishing articles in various magazines, and recently a book on his Sd.Kfz. 11 Late halftrack, which featured in Nuts & Bolts Vol. 20, was published.
