Special Interest Group

The special interest Groups (SIG) are exhibitions of models about a given theme displayed outside the regular competition. Participating in a SIG is an excellent way of taking part in C4-open without any pressure to compete. Everyone is welcome!

SIG – Vietnam


This year marks 50 years since the fall of Saigon, so in this SIG we remember the Vietnam war from 1954 to 1975. All related subjects are welcome, from aircraft to armor and to G.I’s on scooters and both military and civilian subjects.

SIG – Jeep

The Jeep and his cousins

There are few vehicles more iconic than the “Jeep”. It was born in 1940 and has since been used in many forms all over the world by both military forces as well as civilians. It has also been copied by many companies as well. In this SIG we welcome not only Willys Jeeps but Ford Mutt, Bantam, Hotchkiss, Type 73 Mitsubishi, GAZ 67 and other close relatives of the Jeep. Note that more distant relatives like Kübelwagen, Landrover, Landcruiser and Hummers dont fit this SIG. If you wonder if YOUR model belong to the SIG, don’t hesitate to send an email to me. Those who want to enter the SIG, please contact me so I can make room.

Once again, welcome to this year´s SIG:s!
