SHV HOLDINGS N.V.

Talbot-Booth’s rectangular flag of 1936–44 is divided corner to corner into equal halves, with narrower crossed miners’ hammers on longer hafts than the FOTW variant. Rosanoski questions the latter’s field division and red fly where another account specifies orange. He also observes that PAM 31’s lettering is horizontal near the base, not diagonal. Jan Mertens rejects both the proposed 1925 Rotterdam source and a suggested confusion with the 1952 Flaggen auf dem Rhein. The company’s 2012 logo is red rather than the earlier orange.

Mertens describes a flag divided by an ascending diagonal, with crossed miners’ hammers parallel to the diagonal on the white hoist and large white SHV initials similarly placed on the orange fly. PAM 31, built in 1951, is cited as carrying the flag, though Rosanoski disputes what the photograph supports.

The pennant in Flaggen auf dem Rhein moves the hammers to the upper hoist and puts thinner initials horizontally. Michels shows smaller hammers right in the upper hoist, with white dots after the letters. PAM 34, built in 1958, apparently flies it in a black-and-white photograph. Rosanoski finds that company photographs of three tugs support hammers in the upper hoist and letters at the base, rather than centrally.
