Great Reinhardt Bros (Unsigned) Cream Riser

I am proud to offer this very early cream riser. I am sort of stumped on it though. I have a Reinhardt Bros cream riser that is stamped Reinhardt Bros. and this one is shaped just like it but no styamp. It does have inscribed into it 1 1/2 on the side. I know it is very early; but I want to lean towards maybe a edgefield slave piece. I will say it was turned by a master potter. It is light for its size. It's shape is Reinhardt and the lip looks Reinhardt. It is in very good condition with the only apology is the chip on the lip. I have taken photos of the chip for you to examine. It stands at an impressive 8 1/2" in heigth. Thank you and happy bidding.
