Sunpak auto 511 Speedlight/flash   SN 34129839. This flash is missing a grip. But other then that it works good. It works on 4 AA size batteries (or you could use optional AC adapter). This flash is used, but it looks and works good. I would rate it at 8 for the looks and 10 for performance.  Flash shows normal signs of use. It has couple minor nicks and scratches on exterior. But nothing is damaged. Flash works good. It charges fast and produces big flash. Battery compartment is clean. It will be shipped with sync cord, just as pictured.  But grip is missing.
