OTTO WULF GMBH & CO. K.G.

The flag is documented by the company website, Josef Nüsse and photographs. A 16 × 24 cm table flag offered on eBay in July 2007 shows stripe proportions of 1:2:1. Taucher O Wulf 10’s port-side photograph shows a narrower funnel W, with the band and letter following the sloping top. The red bands slope inward at the top, leaving the white narrower above than below.

Taucher O Wulf 4 has a straight funnel top but sloping sides; its bands are angled as shown in W514.
