Everything is buildings in scale 1/24.
The figures have been purchased, some are American diorama, the others come from Germany and the US via ebay.
The diorama is 90% built from nothing, wood, metal, tin etc etc ... Only the bikes were bought from the series Harley Davidson and Maisto 1/24. Very difficult to find the right types, many come from the US, Maisto from the Netherlands and a few dealers on the net. a dozen motorcycles were bought to make parts, others were totally rebuilt, repainted and new things were manufactured such as the side bags, toolback etc ... My years of experience as a motorcyclist and builder of choppers helped me with that. buildings of interest and all that I could find, including the welding machine, the air pump, the oil pumps. Only the gas pump is also a purchase from the USA. NAdien it was completely outdated and adapted to the theme. The diorama is equipped with light inside that runs on batteries and whereby the lights etc. can be replaced. It is currently in great demand for its display. Sturgis in the US is even asking to have it for their motorcycle museum. Surely it cost several thousand euros / dollar in materials during the three years.
