AX-100?

So I ran across this ebay post for an AX-100;
[www.ebay.com]

But the model looks completely different from the AX-100 that is already on generation-msx, the one that is generation-msx is clearly made by Yamaha, while the AX-100 on ebay looks very similar to the AX-170 (Sanyo Wavy style)
Any idea what is going on? Something like a revised AX-100?

I would say it's an rebranded AX-170 because it has the same firmware. But I never saw this one before.
