Recently I bought a Bergischer Löwe from Marktplaats, a free Dutch auction site with a lot of rubbish and occasionally something worthwhile,
At the toe end of the blade, on the satin panel, mine has printed "Dovo No 3 5/8 Solingen W Germany".
Just out of curiosity I checked other pictures on the WWW and found only pics with a similar text without the W.

So, am I right to conclude that my razor was made before the collapse of the Berlin Wall? Were other texts printed on these razors as well?
