Thanks once more for your help, it's much appreciated:-)

Great job, Jens, now I'm happy.

This is NOT "Langer Heinrich" IMO 8959415, built 1915, this is "Langer Heinrich", built 1905 (no IMO that I am aware of). Thanks to our member CybersBase for pointing out this mistake.

For reference see (in German):

(which is the one in the photo)

and

(which is IMO 8959415)

IMO: 8959415
