I usually attend the Battle of Nantwich (https://www.battleofnantwich.org/schedule) and have had in the past been able to take some reasonable photos (though not on film). If there is interest in meeting up armed with film cameras rather than muskets and pikes we can explore possible places to meet up. The weather at the time of year can be fickle (as it was for the real battle) but the battle still goes on and there are photo opportunities in town too, even the chance to snap my brother playing fiddle in the Museum as part of 'Forlorne Hope'.
