It is a VK 111
I am positive about this because my grandmother had this one.
VK 53 (one model before) is basically the same, but it has a green badge and a detachable suction port with a screw. Going to model VK 111 they did away with direct access to the blower fan, so VK 111 had a fixed suction port and all the nozzles were redone to fit this newer model.
The 111 is the last model with a shake-out bag.
Later, just when the next model VK 114 came out, the salespersons started to sell the newer 114 bag with paper filters to owners of the 111.
to get this one complete you can fit all parts from 53 to 115, but to get it complete in the original version, you should take the white straight handle (no vinyl grip) (available with 1 hook, later 2 hooks) and the trapeze shaped smaller green bag (2 versions with or without paper filter).
Hope this helps.
