If you are looking for places around the globe, you can also try ‘Batei Ungaren’. There used to be a ‘Pressburger Minyan’ in/on Meah Shearim (I don’t remember exactly where). But it was shrinking yrs ago so i don’t know if it still exists. The next generation joined Erlau mostly. Possibly they were part of Erlau, or just took him as rav after the war being Ch”S einikel. When they realized he was more Chassidish they separated.
In America they used to call Slichos Ashkenaz what was really Lita. And they did not even print the real Ashkenaz slichos which is closer to Yekkes(except in Washington heights,NY *Yekke town*).
