Bernard Maybeck designed beautiful medieval-style chandeliers for the 1906 store on Van Ness. Those fixtures were moved to 239 Grant in 1909, and later to 239 Post in 1921. Maybeck also designed Gothic-inspired window screens for 239 Grant (you can see some of them at the top of the stairwell); those pieces were moved to 239 Post in 1921 and later to Sutter & Stockton in 1948.
The question is whether any of the chandeliers or window screens have survived. I have not heard of anyone who claims to own such pieces; it has been 42 years since the company was sold, and it is reasonable to assume that nothing is left. Of course, it’s possible some pieces have survived but their owners no longer know their provenance.
