I lost the wind cup assembly for the WS45 Analog Direction/Digital Speed Wind Instrument on my 1966 Bristol Yawl last year during the October hurricane and have had little luck finding a replacement. HS lists the part number as M13349002A Tri-cup Assembly. All of my instruments are HS and all work except for the wind instrument, so I really would like to maintain what I have and just replace the wind cup. Anyone have an old WS45 they'd like to part with?
