[Closed] Clement X'PLOR LZY - available aftermarket?

I'm pretty sure that I've seen Clement X'Plor 700x50 tyres on a couple of manufacturers' bikes (the [url= https://www.raleighusa.com/stuntman-9350 ]Raleigh Stuntman[/url] certainly has them, designated Clement X'PLOR [b]LZY[/b]).

They look just what I'm after (I fancy something a bit wider than my WTB Riddler 45cs) but they're not listed on the Clement site which just has Clement X'PLOR USH (700x35) and Clement X'PLOR MSO (700x32, 36 or 40).

I suspect that there's no aftermarket option but was wondering if anyone had seen them for sale anywhere (I haven't found anything on via Google at present).
