Carlos;
I'm hijacking your thread because your pics are so good!
You state that the company was founded in 1905 and I'm not sure what that is based on but, the corporate records from the State of Illinois find that the company was incorporated on July 3, 1907. Jay G. Rider had 50% of the stock ($12,500) of which $10,000 was paid for in 4 patents assigned to the corporation from Mr. Rider. The company was initially located at 127 W. State St. and filed its first annual report from 313 W. State St. By 1909 they file from the 308 Mead Building on S. Main St. No annual fillings are to be had until 1925 which state that the company is in Ann Arbor, Michigan ad that they were out of business. It was disolved as an Illinois corporation on January 14, 1927.

Not to pick nits, but the founding of a company and their incorporation are not necessarily the same thing. Many companies start out and are in business as sole proprieters prior to incorporation. Incorporation provides a great time-marked event for historians because it puts the company in the public record, but it is not an absolute indicator of when the company started (which I know you know, but just wanted to put out there).
It would still be useful to know the source of the 1905 date, to see if there is a documented record. Until then we can only say they existed in 1907.
None of which detracts from the fact that it is one beautiful pen and an important bit of pen history!
