It's based on a cut down 30/30 or a blown out 219 Donaldson Wasp and chambered in Tenders. The max chamber pressure without stretching the frame is 45K. You can get up to 48K by using .375 Win brass, but you shouldn't have to push it that hard. You could definitely find a viable load for it at or below 40K.

It is an Eben Brown creation, and he makes TC barrels and his falling block guns chambered for it. He also sells dies, formed brass, loaded ammo, etc.

You can find him here: www.eabco.com

And as Stubshaft said, it's based on the 30-30 case so would have the same pressure rating.
