And notice Winter ASI VNE (red radial) seems to be 150kts or 152kts.
Strictly speaking GFA require for issue if Australian C of A an ASI
with markings on ASIs 20 kts over the VNE.
To all considering new gliders ask the factory for an ASI with a
mark at 170kts as have been provided by Achim Winter for more than
10 years and costs noting extra (just ask)

PS several other makers are missing this ASI mark issue also but JS1
seem to be getting it right.
.
So does the 170kt ASI just move the stop a little further around or
is the whole dial scale changed? It doesn't seem to be a standard
product on the Winter website.
So who dreamed up this requirement? Last I looked at CS22 the glider
is designed to 10% over placarded Vne, test flown during
certification to 5% over. An ASI in service that reads to 5% over Vne
would seem to me to be adequate which at 152Kts Vne and 160 kts max
reading on the ASI this one seems to be.
So is this ASI acceptable to EASA? If so why do we have a different
requirement? No doubt our Australian air is "different".
Also interested to know why 95% of the launches were by aerotow?
Engine not working?
