==Apostrophe== 

 Just wondering if an apostrophe wouldn't be appropriate for the title, i.e., "Sigismund's Bell" (per Dzwon Zygmunta)? Sigismund Bell has an awkward quality to it. Another possibility is Royal Bell "Sigismund" (per Królewski Dzwon Zygmunt). Both of these suggestions stem from a more accurate translation of the original Polish names.
