sea waves i want you to check out a similar anemometer ship from along time ago:belfort aerovane or also bendix witch is the same model.120 and the indicator wich is model 135 . the one that you were showing us is a similar cousin of the belfort aerovane. fun fact bendix was a company on 1950s they fabric aerovanes in that time they were grey a black aerovanes but something happend and they decided to rename the company: belfort. so they make a new modern aerovane a indicator with a white modern color: that was the fun fact.well its just that this aerovane its so expencive now. i am a fan of blue hill observatory and they have one and they say it price is $7000 us dlls but this instrument is a legend it was the most sold one in the 50s or 80s and you can find this instrument in us coast guard ships or in observatorys. heres a link:belfortinstrument.com/ambient-meteorological/wind/aerovane-wind-transmitter-model-120/
