No worries at all.
You might be right saying that those rarer Walther pieces like Petri, Haarlem, Victoria comport are easier to find in Australia than in Europe coz a few collectors here I know (including myself) owned a Haarlem centrepiece with the right Groningen bowl and A couple of collectors had the Victoria comport Also, I've seen a couple of Paradies comport in green. You do have something rare and spectacular, and did you miss out naming your spectacular pink Arabella lamp and the amber Lowen clock?
....I am still looking for these pieces myself.
I hope oneday you'll find the Petri for your collection.....Good luck and all the best
