389 Cooper was first built some time between 1875 and 1884, per the Woodburn City Directories. Goad (1888) depicts it as a typical two-and-a-half-storey, brick-on-wood single-family house. It would have likely been front-gabled, like the all-brick #379 at the right-hand edge of the picture.

#389 was converted to the four-unit Tetbury Apartments circa 1915 (per the Might Directories) using the original's low, somewhat rubbly limestone foundation. I'm not sure if the front sun-rooms were added at that time or whether the Tetbury originally featured the stacked wooden balconies usual for the period.
In addition to four domestic units, Might (1916) lists a 389½, occupied by "Harrison Ladies Tailor" — commas and apostrophes being deemed a waste of both time and lead.
The Tetbury name harkens to a small town in the Cotswolds of Gloucestershire, England. Until recently, the building sported awnings at the doorway and front window, which lent a shabby dignity now lacking.
