While a bit off topic and esoteric, the legal notion of hearsay is somewhat nuanced, in a way that might enlighten our discussion.
"Hearsay" is an out-of-court assertion offered as evidence to prove as true the matter asserted. If it is offered for some other reason, it is not hearsay. The reason for excluding hearsay is that sworn testimony of witnesses in the courtroom is subject to cross examination and other scrutiny which is more likely to establish whether the matter asserted is true or not, i.e. is the witness credible? Is the information consistent with other believable evidence? So, as an example,"Fred Bear told me that the star stamp was for no-warranty bows, which could be anything from promotional gifts, dealer samples, deeply discounted bows purchased by employees from the company store". This statement is inadmissible hearsay as to the meaning of the star stamp, but it is legitimate evidence for other purposes,e.g., to show that the speaker had spoken to Fred Bear.
The legal evidence rules excluding hearsay are subject to many exceptions for assertions made in circumstances traditionally considered to be trustworthy. That includes everything from dying declarations, statements against self-interest, statement contained in records made and maintained in the usual course of business or government records.
So even if we cant find any explanations for stamped bows in official records from the factory, I am willing to consider the reliability of information from other sources that is consistent with other evidence, from sources previously determined to be reliable,or given at risk to one's self interest. As an example of the last, a senior member of TG with a two digit member number who has in their collection a 1961 Kodiak with fantastically figured rosewood with a star stamp who says" I picked this up cheap in 1962 as a no-warranty second from the factory store in Grayling" would be more credible that someone with a member number above 50,000 and no previous posts who was selling the same bow with the assertion that the star stamp meant that it was a bow pulled from final inspection of day-to-day production by Fred Bear himself for gifts to VIP's and celebrities and he got it from his mom who was Johhny Weissmuller's masseuse..
