Wind monitor cups

[Damir]

I have STOWE wind monitor this winter during storm cups are blown away.

I have new wind system by CLIPPER but for this i must change all (cable,masthead unit and mastunit to be mounted on side not same as old) and i have no time for it

Temporary i will fix old masthead but i need new cups STOWE ask 31pond+shipping 16 pond + wat? Ifind for this small piece of plastic too much. Have somebody good idea by expirience to find cheaper cups but that pass on shaft or i must going on the mast twice.

Regards

Damir
