Hi Leni - Brockwitz glass is a passion of mine, so it has been a case of searching for years to get the Lion bowl. Ours is a blue one, and in fact I bought it from a German seller.
I believe that there are 4 different "creature" handles (one is fishes

.... ooh, weird grammar!) Fish, birds (budgerigars?), squirrels and lions. I have a blue squirrel handled bowl (also from Germany), a pink fish handled bowl (bought in the UK) and a bird handled vase in amber (bought in the UK years and years ago). (There's also the vase with the two little birds, but they are not handles).
It's possible that the rarity / trade policy, marking etc., of these has been covered in Siegmar Gieselberger's discussions, but my German is non-existant and so hopefully Pamela will be able to throw some light on all this. I can say that one of the German dealers who I bought from told me that Brockwitz exported most of their decorative glass (Carnival and these splendid items included). I can't verify that, so I look forward to hearing from Pamela.
