Richard posted a little info about them a while ago.
Doesn't explain the seemingly endless supply of something discontinued years ago though.

The W2298 Last was used for the long discontinued (3 years ago) Tricker's 'Corniche' collection. These models were 'Country Style', but regular fitting and Lighter weight. Most of them had Storm Welts, but Single Leather Soles. There were a couple of Commando Soled models that had a Leather Mid-Sole fitted.
You would also note that the boot is fiitted with a Flat Welt but the Sole Edge is kept to a fairly Wide Trim.
I personally wouldn't consider the bot to be 'sleek', but it definitely has a little more 'shape' in the Toe than the regular 4497s Last of the Stock Stow.
I like it ;-)
