Solarforce fans: New mystery tailcap?

Solarforceflashlight-sales.com is selling an Ace L2P Stainless Steel set DIY flashlight body with an "S11" tailcap. But the original S11 looks like this and this. The so called S11 on the Ace L2P has a fat body that looks more like an S8 that's been given some stainless bling. I wonder if this is really a new S13?

Its a S9 tailcap

Thank you for satisfying my curiosity, and for the link. Now, to hunt one down.
