This listing is only for the battery holder (magazine) fitting the Sunpak Auto 411 flash.  Probably works in the other Sunpak flashes that have this same style ( but please confirm.)

The holder is in good condition with some light surface marks.

Holds 4x AA batteries.

(If you'd like the 411 flash this holder came out of, you are welcome to it.  Just pay the extra postage.  The flash body adds 1 pound to the shipping weight.  It fires reliably, but I don't think it is hitting 100% output every time. The shoe shoes signs of epoxy, so may have been repaired at some point.)

Thanks for looking.
