FERNSTRÖM.

Collectors Corner’s second flag corresponds to F82. The colours of its stars and waves are unclear and do not seem identical to the letter. Mitchell’s funnel differs: a lighter blue, closer to F81, a plain “F”, two small triangles instead of stars and two wavy lines rather than three.

F262 comes from the Bryggan website; its flag illustration was credited to Jarig Bakker.

A second flag has a lighter blue field and a slightly ornate “F”. The US Navy source supports it under Erik Fernström, although its letter is not entirely clear.

The stem jack is a horizontal yellow-over-green bicolour with a black animal on the yellow. The animal appears to be a horse.
