This one is probably one of the 1st serie. Imported from England to Portugal by the trader J.J.Ribeiro , from Lisboa, probably changed the front label to their own name. However all stamps from Lancaster & Sons are visible.
I've found it last week during my holidays in Oporto, in very poor condition. After 3 nights of work this beautiful camera is ready for a second life.
