The piston fountain pen described is definitely no Montblanc; the material rather looks like post-war plastic, while the form recalls the 1930s, which points to a so-called no-name manufacturer. With the Safety pen, the nib clearly comes from Montblanc, but whether barrel and mechanism are also original parts can only be clarified by inspection. Since Montblanc at that time was already a premium manufacturer and children did not count among the target group, an advertising campaign with the children's magazine Rama-Post is very unlikely; manufacturers like KaWeCo or Soennecken would come into question.
