I never heard of thuringer. I was curious if a bologna sold here was considered a summer sausage so I googled it. Pa dutch area eats Lebanon bologna..good in a sandwich and good spread with cream cheese and rolled up..here is what Google said

Lebanon bologna is a type of cured, smoked, fermented, semi-dry sausage. This all-beef sausage similar in appearance and texture to Salami, although it is somewhat darker colored. Lebanon bologna has a distinct “tangy” flavor, more so than other fermented meat products such as summer sausage.

If your deli sells it, give it a try
