The sheed duck was a contest. All the ducks should have a number on the bottom. They were Reales ed in the Willamette river and raced from a to b. Not sure how many were released or what the contest was for. I was in the military during the event.
I check ptb every day on ebay. I've seen it for around 60- 120. I think that price is ridiculous so I'm waiting to Find it at an estate sale or something like that. It's a great piece either way. Good luck on the rippy
