The Brooklyn Eagle in 1893 published notice of plans by builder David Atkin to erect a row of 9 four-story, 4-family flats in this location, so we suspect this is the very same row, still standing if a bit worse for wear.
Brooklyn Eagle, March 10, 1893, p. 6 ("New Buildings and Real Estate")
The cornices that remain show an interesting scallop-shaped design:
We have associated builder David Atkin (a.k.a. "Atkins") with a few other buildings in the South Slope, most notably the 1889 mixed-use (flats over stores) row at the northwest corner of 15th Street and 7th Avenue. Our research files show both "D. Atkin" and "D. Atkins" operating out of 339 15th Street, a building which he also built in 1889, together with the 7th Avenue row.
