Ich bin's nochmal...
I've added a changeset after more research (and fixing a networking problem that kept me from seeing much).

fkv, you added housenumbers for Sepp Eybl, the E-Werk and the Atelier (also found with address 50), all In der Noth.
In the Bing/ESRI DigitalGlobe satellite imagery I can see another building not mapped, near Nr.23 on Prochenberg as renamed, trustworthily, by Herr ThomasHoch (matching background basemap.at label).
I've added this house and copied the address 51, also adding the streetname visible from basemap.at -- this differs from your use of hamlet for address Prochenberg; as an outsider, unfamiliar with local customs, I welcome any corrections.
It seems the boundary between streetnames Prochenberg and In der Noth is the Prollingbach bridge, based on the background map.  I don't know how to correctly rename that.  I searched for text info about that without success, but I did find that Prochenberg 23 is an address used to refer to the chapels to the north of this note. ;-)
Please do not hesitate to correct my remote armchair (minimal Ortskenntnis) mapping!
(now to see if I can add more, having opened an editor, may as well make good use of it)
