Anyone have Wossner 400 pistons?

[julianharty]

I've just bought one (not two) complete NOS Wössner pistons labelled SK170137 MotoMorini 400, diameter 65.93mm. It's beautifully manufactured and was inexpensive. However... one of these pistons isn't ideal and at least one more would be encouraging please let me know if you have any of these. Conversely if you need one, I have one available.

FWIW I have 2 bikes which are approximately 400cc, both with gilardoni barrels. This pistons doesn't match those ones.

Meanwhile I'll email the manufacturer to see if they have any more NOS items.
