British Birds from Blade Runner

In this ongoing series on Top eBay Chess Items by Price, sometimes I see an item that just begs to be chosen. A good example is pictured below. Titled 'British Birds Chess Set Blade Runner Movie Prop', it sold for US $800, after receiving 27 bids from 12 bidders. The description started,

As a huge fan of the Blade Runner movie, I was interested in the chess set J.F. Sebastian had in his home. Here's a screen capture of the scene where you can see Roy and the chess set.

Two other photos from the auction page are shown in my composite image below.

The description continued,

A few of the birds have a few defects, including beaks that were broken off. You can see the missing pieces in the photos. I did a lot of sleuthing to find out where these were made and went through a lot of trouble importing this from the United Kingdom. These are no longer made. The original set was made by a company that is no longer in existence.

Unfortunately, the 'company that is no longer in existence' wasn't named. If you're interested, you'll have to do your own sleuthing.
