Having a passion for construction equipment started when I was very young. Looking at construction places to watch draglines, scrapers, dozers, loaders and dump trucks. I could spend hours just to watch them. I got in 1975 a training for service engineer for a Dutch Bobcat dealer and from that time my favorite machine had a white colour. Traveling from January up to December in Europe, Africa, Middle East and Russia means meeting many people with same passion as me namely collecting construction models. I visited many collectors over the world to see their collection. To see and to learn about displaying models.
