Deletion of 105 mm

Comment: no valid argument for deletion presented; all comments above are instead about fixable problems or are contra relevant guidelines on lists and categories. Clearly if the individual entries are verifiable, then an index of them together is as well, and it's just a question of migrating sources over from those articles. The nominator even "assumes this content could be sourced", which means per  and  that deletion for lack of present sourcing is off the table. We're not talking about contentious BLP material so there's no deadline. Most of the entries in :Category:105 mm artillery even have the caliber as part of the article title so it seems silly to me to even consider that a problem
