Mercian? they’ll build exactly what you want, or look for a second hand one that’s ‘close enough’
thats a ‘93 King of Mercia built to take 700x32c with guards, will actually take 35s under them if you squeeze.
Geometry is custom but based on their Audax/Soort tour and it’s built from 531c
if you asked them today they could build exactly the same thing despite the 30years gap, although would probably offer 631, 725 or 853 instead of 531 but that’s not a problem as the modern equivalents are as good or better.
other builders are available in the UK too, insure you must have some in Germany? Alternatively look to the French... Gilles Berthoud still build traditional random eyes, as do others (including Cycles Alex Singer if you have deep pockets!)
