Rali 220 Hand Plane - Made In Switzerland

In a box which advertises a smaller plane as well but this is just for the 220.

Base around 8 5/8" x 2 1/8"

Looks to be in very good order but there is a rattle inside it, like there is something loose inside it but can't work out why that is.

Uses spare blades rather than sharpening one, comes with the blade with it but no spares.
