    It is the seal of the certification authority, "Prüfdienststelle für
    Technische Schiffsausrüstungen", the 'verification department for
    technical ship equipment'.

    I'm not sure about the number. I'm inclined to think they identify
    design specifications, since all the 62's I found via image search are
    alike, while the one 58 and the one 61 I found differed from each other
    and from the 62 in drum design.
    
    On many Freiberger sextants there's a different stamp in that location
    consisting of the letters DSRK arranged somewhat like the cardinal
    compass directions:
      S
    D R
      K
    
    This was also an East-German certification society:

    You could look up the book 'Material- und Warenprüfung in der DDR' by
    Fuhrmann e.a. if you were really keen.
