In light of the interest in S&P silk tallitot, here is a picture of The Great Synagogue (Sydney) clergy in the 1920s or early 1930s. All are wearing S&P tallitot, or at least in the S&P style. This reflects a general S&P influence on English and Commonwealth Ashkenazim. Another example is leading services from a bimah towards the back of the synagogue and seats facing the centre, not the front.
