Calvin Sideboard Info?  

I am restoring this lovely sideboard and would like to know more about it. I can only find one reference to it, on 1stDibs, that says it was manufactured by Calvin Furniture. Calvin is best known as the manufacturer of Paul McCobb designs through its relationship with B. G. Mesberg National Sales, but it doesn't look like a Paul McCobb to me. I'm wondering if it could be a Kipp Stewart, since Stewart also designed for B. G. Mesberg in the late '50s. It kind of has a Kipp feel to it. Anyone have any ideas? I've looked in all the standard places, and could only find the 1stDibs reference, so it might be kind of rare. Don't really know, but it is beautiful, isn't it?
