The Wilkin & Sons factory in Tiptree keeps a free museum in a converted farm building, where old preserving machinery sits beside packaging through the decades and a taxidermied four-legged chicken. The collection began when one Wilkin rescued equipment and papers bound for the scrap heap, and it includes a letter from Gladstone, whose 1883 speech reportedly inspired the founder. Allow 30 to 45 minutes, plus ten for the video on how the fruit is grown.
