Only a few
Albatros C.XV aircraft were delivered before the Armistice. Sources are divided on whether it saw action in the closing months of the war -- we know only that it did not show up in the last
Frontbestand records of August, 1918. For an Albatros two-seater, it was unusual in having widely staggered wings. After the war it saw civilian use.
This model comes in several scales. The 1:285/6mm/1:288 product contains two aeroplanes connected by links. In fine detail plastic, those come with detachable propeller disks. At 1:600 and 1:700 there are six planes connected on a disposable sprue.
