"Awww, this is the perfect image Gary. Looks like the duck is posing for you and just the way the feathers have displayed, and that one gorgeous blue feather showing that is a dead giveaway for the id of this duck. It is so right…"
I ordered it through Henry’s in Halifax. I placed the order July 16, they told me it wouldn’t be delivered until the end of the year/new year (i.e. now), but it came in on Aug 28, so a month and a half wait.
The above was a quote from my friend who sold me the 500 and bought the 400mm DO.
I hope that helps.
