Seems like a rare item; interior "trimmed in tarnish-proof 'canyon copper' no polishing needed." Lots more pix in the ad on SF Bay Area CL linked below.
that anything so old would be still around, in Russian Hill, or anywhere in S.F. really.
The houses all look very high end, and are thusly high priced.
I think of Viking appliances, Sub Zero, Wolf, Gaggenau, or Bertozzoni and LaCourneau ranges in those homes.
I didn't even bother to locate the ad for the range. On any given day, there are multiple listings on SF Bay Area CL for Wedgewood and OK&M ranges in that old school style that both manufacturers retained for far too long. I find them boring, and wish my sister would upgrade from her frumpy Wedgewood to something more MCM in style.
