The Anderson Wheeler is cool, but has become vaporware. Everyone I know who put down a deposit lost their money officially about two years ago, as a company it seems they have either gone completely out of business or have severely changed the way they are operating. Attempts to get in touch with anyone who was associated with the company is met with radio silence. Their website is down and their London storefront is gone.
I never saw anything but the one gun which they brought to all their exhibitions, it is the only known prototype as far as I know. However they did prove that the gun could be made in a .357 at all, which is more than a lot of companies making reproduction revolvers have done. Similarly the PHSADC Webley Fosbery was supposedly ready for market almost 8 years ago, but I haven't heard anything on this front in ages either - at least they published images of their production prototypes.
Other than the Italian repros, there is the NAA Mini revolvers which they made a top break variant of, called the Ranger I believe. Additionally Webley India still produces the MKIV Medium frame in .32S&W Long where it is sold for concealed carry there. Neither of which we will likely ever see in Canada of course, even if the freeze is undone.
