Why did you use Eastern German polyester caps in there? I've got bags full of those, and they don't sound nice at all to my ears. Some sellers here in Germany mistakenly sold them as polystyrene, but that's not what they are.
Looks very nice, accurate build!
Poly or not, those old Deutch caps sounds nice to my ears. The rest is matter of taste.
A couple of questions. Hardware bypass?
