Good translation Doug!
CD are the points on the disc where the fisherman's feet (C and D) are attached.
Point F will be the point around which the legs and body rotate.
Rickstef - reading through the rest and given the above, it appears the assembly may be as follows......
- Feet attached at points C and D.
- The body needs to be joined at the hinge point (F - which I suspect is not clear because it is a small black F).
- The flap cut out of the base will control the fishing movement. For this to work you will need to attach a weight to the upper front part of the body.
- Holding the base and pushing the flap down (to the right) will "bob" the fisherman.
The idea I guess is to do this to try and hook the fish - a kind of early fishing toy!
Interesting find!
