Moser, Josef Hoffmann?

I was quite taken with the chunky shape of this vase when I bought it from a charity shop a couple of years back, but thought little of it. Had it rolling around the boot of the car for a few months, then left it on the front wall collecting rain water and green slime until today. While researching another Deco vase earlier I noticed that it was similar to a Josef Hoffmann-designed Moser vase. Would anyone with superior knowledge (and in this case, that's barely above nil) care to cast their eye over the photos and offer an opinion, please? Height, btw, is 19.5cm.

Sadly not Moser but Rudolfova Hut, designed by Rudolf Schrotter, pattern No. 11558/A.
