Is this a redial constellation piepan ?

I just did exactly this, well its not a bad one but it is a 168.004 PP. Yes I am prepared to suffer for my art. I'll report back when it arrives.

Haha. If you pm me your bankaccount or paypal f&f I will wire the eur 100!

No need. I'll take this one for the team. Will post pics when it arrives. 👍

Holy thread revival Batman. I am a man of my word, the newly acquired hidden crown 168.004 mentioned above was serviced recently, link to many pics below and a couple of close ups I took. I'll be honest and admit that there is no obvious step or plane transition at the scallop edges on this so much as it pains me to admit it, @Dan S might have had a point above, at least with respect to the hidden crown models. I can't say I've seen a dog leg or curved lug PP with an obvious tromp l'ceil effect as yet, but this hidden crown example hasn't got much of a kink at all and much of the effect is in the dodecagonal shading. It might have a slight bend but its so smooth as to be near imperceptible. Maybe at the date window can you just make out a plane change. See for yourself but it maybe that some kinked scallops on PPs are more obvious than others.
