From Curtis Clay: This type is known for Diocletian from officinae 1-2, 4-5 and 7. For Galerius there are coins from officina 3 (added: 'Known also for Maximian, RIC'!). For Constantius coins from officina 6 (S) were expected but not yet known.This can be changed when more coins are coming out of Turkey or Syria
