Hear ye, hear ye, hedge fund honchos: There’s about to be a rare apartment for sale in the quiet half of 740 Park Avenue, the anti-chic “back of the bus” apartments that use 71 East 71st Street for their address. June Speight, widow of a former co-op board president (and one of the last of the old breed WASPS in the building), died this past weekend, which means that apartment 4/5 C (you can see an equivalent floor plan here) should be on the market soon, priced somewhere around $30 million. The last sale in the building, of the somewhat larger apartment 4/5A facing Park Avenue and using the front entrance, to David and Tamara Winn, fetched $32 million.
