The FlipFlash is a double ended 4-shot array of flash bulbs designed for use with certain old school film cameras. As shown, the example on offer was manufactured in Germany by Porst. This vintage item has been lying in my spares drawer for years. None of the bulbs have been used and the electrical contacts appear to be in good condition but whether they will still work is anyone's guess. Selling as a curio, museum piece or collectable. Enquiries: please ring and ask for Charles. Pick up: Springvale Victoria. Postage: $2 Australia wide.
