  The Asiago photographic archive has been searched for plates containing the
symbiotic stars Hen 2-468, QW Sge, LT Del, V407 Cyg, K 3-9, V335 Vul, FG Ser
and Draco C-1. A total of 635 plates imaging the program stars have been found
and the brightness estimated using the Henden & Munari (2000) UBVRI photometric
sequences. These historical data have allowed for the first time the
determination of the orbital periods of Hen 2-468 (774 days) and QW Sge (390.5
days), a significant improvement in the orbital period of LT Del (465.6 days)
and for V407 Cyg an evaluation of the Mira's pulsation period and complex
lightcurve shape in the red (R and I bands). Some previously unknown outbursts
have been discovered too. (Paper I: Munari et al. 2001, A&A 370, 503)
