Please do follow the directions that Jaybird gave you. You can set up a free account hosting images on Flickr, then use that "Canera Roll" address to post the image here. We'd then be very happy to try finding a year for your fins. David Richie Wilson in Great Britain is an internationally-known expert on fins made around the world. Welcome here, and Merry Christmas.
John C. Ratliff Diving since 1959, at age 13. Haven't stopped, and still enjoy getting wet.
