• The research literature on the star V448 Cyg is reviewed in more detail. An analysis of three color photoelectric observations made at Abastumani is reported in detail with corresponding tables and graphs. In particular, the gaseous structure and evolutionary status of the system are discussed. Newly published spectroscopic data suggest that our light curves might be interpreted by more modern nonclassical methods assuming a new model. Thus, comparing data obtained in this fashion with the new spectroscopic data may help improve the evolutionary status and model for the V448 Cyg system. It is also seems possible to obtain better values of the physical parameters for circumstellar structures and obtain more precise information on the physical conditions in the atmospheres of the stars and on the structure of the circumstellar shells.
