That lock was made no later than 1925 as lever locks were rarely made after WWI in the USA. I would guess around 1890 if I was to guess. No being 3000 miles away (Seattle, WA) does remove a bit of what types of locks are common here. Most buildings from that time are rare. Those that are have mortice locks and not surface or rim locks. Unit locks are common from that time and so are Mortice locks. I think that since the Mayor of Seattle Byron Phelps 1892-1894 and King Co Auditor 1900-1924 invented the Corbin and Russwin unit locks that became one of the common types of locks around here. He seemed to have some pull with the men of power from that time.

After looking at that logo I would say that it is before 1905. I have several key blanks with a newer logo from 1905.
Lastly that is a Russell & Erwin Co. lock.
