Looked at some sources for more than a hundred times but needed the help of my german forum mates to poke my nose onto this detail and I was able to put the puzzle together.
There are some helm indicators shown in NMM one of them on a ship that is quite dear to me ;-)
And both shown examples on contemporary models!
SLR0512 Scale: 1:60. A model of H.M.S Victory (1765) made entirely in wood that has been painted in realistic colours with metal fittings. The vessel is shown in a launching cradle on a slipway. The hull is painted white below the waterline with a closed black wale above. The remainder of the hull is varnished, and laid in individual planks. There are three gun decks and all the gunports are depicted in an open position, the inner faces of the gunport lids are painted red as are the insides of the gunports themselves. A decorative frieze is painted on a blue ground that runs the entire length of the hull just above main deck level. The figurehead is finely carved depicting George III, allegorical figures and a Union flag on the starboard side. Other bow details include a pair of whisker booms, a pair of catheads, one large admiralty pattern anchor, and one small anchor. The model does not have any masts but instead has three launching flag poles. Foredeck fittings include a bell and belfry, stove chimney, and a forward launching flag pole. The waist has been closed in and four beams support a ship’s boat equipped with a number of red-painted oars. Beneath the boat on the main deck are two sets of gratings. The upper deck fittings include the ship's double wheel painted red, and two companion ways that provide access to the poop deck. The poop deck fittings include a rectangular skylight, launching flag pole, hammock stowage rails, and provision for an ensign jack staff. The stern and quarter galleries, of which two are open, are elaborately carved and painted, and glazed in mica. The launching cradle and slipway is realistically depicted and there are six stabiliser poles attached to the port and starboard stern quarters and the sides of the slipway.
Date made Mid-18th century
Also to be seen on the Royal George (1756) in NMM, rather small but if one compares to SLR0512 one can see the same thing:
SLR0336 Scale: 1:48. A contemporary half full hull and half skeleton model of the Royal George (1756), a first rate, 100-gun three-decker ship of the line, built in the Georgian style. The model is partially decked and has the name Royal George painted on the counter of the stern. The starboard hull shows plank on frame while the port side is unplanked to show the internal construction and layout, including numerous fittings such as galley stoves, capstans and cabin furnishings.
Date made circa 1772-77
And the last thing I needed was to be dragged to the detail in the red square on the Turner drawing ...
