A841’s funnel comes from a starboard view of Alsterbach; Rosanoski thought its unusual proportions probably resulted from the charter. The flag has a green leaf with black veins between two horizontal green stripes. Klaus-Michael Schneider considered it probably a chestnut leaf, having seen the flag at the company building on Hamburg’s Außenalster on 22 August 2008. Eugene Ipavec questioned how recognisably the drawing represented a chestnut leaf.

A842 combines a photographed funnel with a rectangular website image presumed to represent the flag. Both use darker green than the FOTW image, and the website name differs. Zillertal is recorded with the A842 funnel on 30 September 2011.
