Sunpak Auto 444 D Thyristor Flash w/ NE-3D Attachment for Nikon F3 F3HP F3 HP
This is a nice flash for the Nikon F3/F3HP. It comes with the Sunpack NE-3D attachment to mount the flash directly onto you F3. The F3 does not have a regular hotshoe so this is what you need to mount and shoot this flash.
It is in excellent condition with light wear and works perfectly. The battery compartment is clean.
