Yes it is quite special in its details, while conservative in its overall appearance. Also note the very high closing waistcoat.
I am always on the lookout... but hard enough to find anything larger than 38 and it is 99% black stuff. I have the ominous feeling that a whole lot of brown, grey and green suits of the past, have been altered into traditional Bavarian "Trachten" costumes througout the decades. Particularly flanells and woolens probably all too often shared this fate, but anything brown or grey can be turned into a Trachten costume by inserting red and green felt ornaments and botching collar and lapels.
