I've run into a small problem identifying the German naval vessel from which a postcard was mailed, and I need some help trying to decipher the German handwriting in an attempt to ID the ship.
The card is a Marine Schiffspost card mailed from a German ship, but the number on the MSP cancel is poorly struck. It definitely ends in a "6" -- I think it's a "16", but it was advertised as a "36" when I bought it.


If it's a "16", it would have been mailed from the school ship
SMS Charlotte while on a trip between St Petersburg and Kiel, specifically while in Kristiania (Christiania), present-day Oslo, Norway. Here's what a "16" cancel should look like:

If it's a "36", it would have been mailed from the cruiser
SMS Geier while in Vera Cruz, Mexico.
I've tried to get clues as to the location from the text on the reverse, but the handwriting is a challenge for a non-native speaker. If anyone can read the text and shed some light on the answer, I'd be grateful.
