Brown Saltman Bench with Cabinet ID?  

This is a Brown Saltman Bench with Cabinet. I got it at an estate sale near San Francisco, CA. The cabinet slides on the bench and it has two doors with cane webbing. The house I got it from had an identical bench but with glass sliding doors. Trying to figure out who designed this for quite some time now. I have searched everywhere online and nothing similar by Brown Saltman. The only thing I've seen close to this is a Paul McCobb bench but it's very different.

The person I bought it from said John Keal but was unsure. Can anyone confirm this?

It is stamped on the bottom of the bench.

Would really appreciate all your help!
