OLDENBURG-PORTUGIESISCHE DAMPFSCHIFF-RHEDEREI GMBH & CO. K.G.

The date of this funnel is uncertain: Merchant Ships 1942 describes it as a former design, whereas Ships & The Sea 1936 says it then applied. Rosanoski doubts the latter date because Talbot-Booth’s 1937 and 1938 publications do not mention it.

The funnel shade follows OPDR Las Palmas, photographed on 26 May 2005 while employed by FOCS. Website flag illustrations include a dark blue version. The FOTW description gives a blue flag with a red St George’s cross and white initials, transcribed there as OPDG.

The blue flag has a red cross extending to the edges, with its intersection towards the hoist. These are Oldenburg’s state colours. White O, P, D and R occupy the upper hoist, upper fly, lower hoist and lower fly respectively, close to the crossbars. The proportions are estimated at 1:2.

The Mobil chart shows an orange funnel.
