Piaggio108

Which is more correct, Fiat C.R.42 or CR.42 or CR42? Also, what is the deal with SIAI Marchetti vs. Savoia Marchetti? Am I right in thinking there should be no punctuation between German abbreviations and numbers (like Bf 109)? Also, is it correct to call post 1938 109s Me 109s or are they still Bf 109s? Is the first letter capitalized in these abbreviations?
