Thanks Anik!
The Vizner is so huge and heavy, a really impressive lump of glass...
As the bowl has the exact same colours as
>> this one I showed a few weeks ago, I have not much doubt it is Skrdlovice and from the same "range". I still struggle with the PN.
Funnily, it was sitting amongst several pieces of Chribska when I spotted it

The one in the catalogue you linked to seems to have pulled lobes at the underside, so I would think rather not...
edit: Forgot to mention: it has an engraved "II" at the base, which we have seen before in Skrdlovice from that period.
