This is Sunpak Auto 522 Thyristor flash.  The flash will charge and fire using batteries.  I connected the sync cable to a camera and the flash fired when the shutter was released.  I have not thoroughly tested this with a camera and have not tested it with film.

Please make sure you read and understand this before bidding.
- I am happy to combine shipping on most items.  Some are less expensive to ship in separate boxes, or will not fit in one of my standard size shipping boxes.  If you want to combine shipping, contact me before paying and wait for an invoice.  If you pay without waiting for an invoice, I will not do a partial shipping refund.
- Make sure you know what you are bidding on and what is included or not included in the auction.  You will not receive batteries, boxes, bags, certificates, instructions, or any other item not mentioned or pictured.  If it doesn't say it in the description, you probably won't get it.
- I will not end auctions early, change an auction to Buy-It-Now, change a public auction to a private auction, or break up lots.  Don't even ask.  If you ask, you will not receive an answer 
- If you want to wait a couple of days to pay, please contact me before bidding.  I'm usually willing to wait until payday or until another auction ends so you can combine shipping, but I will not wait an excessive amount of time.  I don't have storage space to hold items.  Payment is due within three days of the end of the auction unless you make other arrangements with me before you bid.
- I am not responsible for items getting lost in shipping.  Once I turn the item over to the USPS, it is on them.  I ship everything Priority Mail unless otherwise stated.  I pay for extra insurance and signature receipts out of my own pocket because I don't want either of us to lose money.  If something has been shipped but you do not get it, please contact the USPS first.
- I am also not responsible for porch pirates.  See the last bullet point.  Anything that sells for $300+ is shipped signature required to protect you.  If you want me to include signature on items under $300, let me know.
- I do not charge anything above standard USPS rates, so please do not complain about shipping costs.  I have no control over this.
- Because of the age of most of the items I sell, there may be flaws of which I am not aware.  I try to describe the items as well as I can, but I may miss something.  Therefore, all items are sold as-is with no warranty or guarantee.  Please look at all photos and ask questions before bidding.  
- I do not live in a pet free home.  Some items may have some dog or cat hairs and dander that have floated onto them.  None of these items were played with by the dogs or cats.  Please be aware of this if you have pet allergies.
