Loeschcke Typus X = Broneer Type XXVI = Dressel Form 5 = Iványi Typus XXVII = Evelein Type A3 = Bailey Type N Group iii (Late Flavian-Mid-Antonine, North Italian).
Late Firmalampe from workshop FELIX, poorly executed (ledge and mold impression, off-center filling hole, no airhole, degenerate nozzle-termination rim, signature upside down), though fabric suggests still northern Italian (or e.g. Pannonian?). Based on discussion by Bailey (BMLII, pp. 274-275) our lamp probably belongs in the early to mid-2nd century.
