Vino-Seal Question?

I would really like to find a half bottle of anything sealed with the glass stopper Vino-Seal. I have plenty of 750 ml. bottles
( Austrian/Cal. Cab.)sealed that way but it would make spliting a full bottle into halves so much easier. Has anyone seen Vino-Seal used on 375 ml. bottles?

It appears the bottles actually exist in the 375 ml format. Go to http://wiegand-glas.de and look at bottle numbers 143 or 176. Now you just need to find someone who uses these. BTW, this type of closure is known as Vino-Lok in Europe (first developed by Alcoa Germany).

Thanks Joe for the link. Now I'll have to do some asking around at wine shops.
