Photos are gone for comparison, but note...Reed & Barton top-marked a silverplated teaspoon Columbia in script. It is an un-determined user so far. Possibilities are numerous including ships, riverboats, a Chicago cafe, a school, etc. (This has nothing to do with their sterling Columbia pattern.) Elsewhere, another thread mentions the use of a full name like Columbia Silver Plate Company.
Addt. Info.: A Reed & Barton Muffineer was previously sold mis-identified as San Francisco & Pacific Steamship Company where the correct name should have been San Francisco & Portland S.S. Co. (found on Worthpoint site). The S.F. & P. was the operating line for S.S. Columbia shortly after Union Pacific Railroad gained control of the Oregon Railway & Navigation properties. This may connect Reed & Barton, indirectly, to silver services that may have been used on this particular Columbia (famous for it's early use of electric lighting). Columbia ran the Portland-San Francisco route for several years prior to this technical re-assignment, and was lost at sea in a colision related holing, rapidly going down at the bow as Titanic would a few years hence.
