Oh no! The Vikings have a trebuchet! (Well except it doesn't work properly, but still, imagine a fierce combination of these bloodthirsty raiders and such a destructive tool of war!)
This is a large siege weapon constructed mostly of pine wood, the counterweight consists of a wooden box and some coins. It has a working mechanism and will be completed with gadgets to pull it to firing position and release once I'm getting past the slight trouble it has right now. The basket into which the projectile should be placed is a small piece of cloth and the thing falls out of it sideways when it is launched. It requires some more experimenting but I thought I would show you where I stand right now.
It is about 20cm tall so quite a big one.
The six 1/72 Zvezda Vikings are by the way totally unrelated and included only for scale comparison.
