(Helen) Rene Dumont was a very popular Dorfler & Jorka stencil. However, D&J did not make baris. When they had an order for baritones, they outsourced that order to another European company. Which one? No one can say for sure. European saxophone historians I work with are not clear on that.

I am not convinced that this is a JK bari. But... we had to put it somewhere, so it landed here.  

Notice the following: 1. It has a D&J serial #. 2. It has D&J engraving.
