From Graham's picture I would certainly agree that the tops of the vases are identical. It would seem logical to me, and typical of the czech practice to simply the designs for "mass production", that they were Hospodka. I've seen many of the vases like Emmi's at fairs etc and they all seem to come in the typical czech colours aswell - such as the citrine and lilac colours that the common Klinger pieces are found in.
Hi Richard, whilst I agree there's a good likeness in the rims they're certainly not 'identical'. If you look at Emmi's and my vases again you'll see that the eye shaped rim is totally horizontal, the one in the catalogue that Graham has shown is slanted upwards. So when you take into consideration that the body shapes are also very different all we've got between the original vases and the catalogue photo really is a similarity in the rim finish and not a lot else.
*Edit* with regard to the colour and frequency of these vases - being a dealer I'm constantly on the lookout for glass at auctions, bootsales, charity shops etc and I've only seen 3 of these vases in the flesh in the 5/6 years I've been doing this and they've all been the same dark bluey green colour. I personally don't think it's sensible we should use items members have *seen* but not shown, as confirmation that they were produced in other colours and therefore must be Hospodka or whoever - it's all way too tenuous IMO - they could be completely different vases.
