`Nova Aquilae No. 4', discovered in 1919 and later renamed V605 Aql, was only recently recognized to be a final helium flash object. Clayton and De Marco (1997) have given a detailed description of the available spectroscopic and photometric material. We have tried to re-analyze the photometric record. While the photographic material is still available and has been used to compile a revised light curve, the visual observations are only partly published and appear to be lost.
