Yes, you are correct; this is a captured Russian 15 cm gun. The sender mentions it was prohibited to send such cards openly, i.e. without envelope – actually, even taking pictures of these guns was not allowed.
Transcription, with added commas and some corrected spelling:
Lieber Richart und alle, muss euch mal eine Photografie von unseren Kanonen senden, es ist die russische 15-cm-Kanone, Beute-Geschütz, ich bin leider nicht mit oben, ich bin beim 4. Geschütz, es ist verboten die Karten offen [zu] schicken, sie sollen schon nicht photografiert werden, aber nur das eine, Herzlichen Gruß sendet …

Note the short carriage favored by Obuchov. Ironically for these fellows, this is probably a Krupp gun, sold to the Russians prior to WW1.

As opposed to today when the Libyans can see as many photos as they want and openly read up on the full coalition deployment, leadership and coming plans on Wikipedia-

Crazy world!
