Probably from the 1950s/60s these vintage "COMPASSES FOR STUDENTS" are rather unusual in that they have a graduated wing to set the distance, in cm,  between the pencil and the point..I've never seen compasses like this before !
They were made in Peking  (now Beijing) China and come in little paper wallets.
They all have pencils.
And they all have a bit of rust somewhere on the chrome. (see last picture)
