Regarding the proposal addressed to General James Allen and made by the Wright brothers on January 27, 1908, where are that included photo of the 1905 Flyer and those drawings the Wright brothers wrote about in their letter?
I found the Wright proposal of January 27, 1908 in an article entitled "Wright Brothers' 1908 Proposal for a Heavier-Than-Air Flying Machine," on page 32 of an excerpt from the Spring 1999 edition of "Proposal Management," a professional journal of the Association of Proposal Management Professionals (APMP):

Neither the referenced photo from 1905 nor the drawings are included in the article. The authors' bibliography (p.36) may give you some leads if you want to track them down.
