John if I may offer somewhat of a defense of Scott, who certainly does not need me to defend him, I don't believe I've ever read a post of his which in anyway argued for or against the merit, quality or otherwise of any gun under discussion. As far as I've seen, his postings almost solely focus upon any period / 1st hand documentation, and interpretation of such documentation. Discussion and debate in regard to documentary sources in no way denigrates any given piece, in my opinion. For far, far too many years, there has been a huge abundance of inaccurate, shoddy, or otherwise downright false "documentation" surrounding many of these old guns, and I for one find it very refreshing to see a demand for accurate and provable information.
As Earl Lanning said numerous times when he used to chime in here (and I paraphrase somewhat), there's nothing wrong with saying "I don't know." Speculation is great fun, and can be useful at times, but it should always be accompanied by the caveat that it is speculation.
Anyway I don't see the problem? I for one am very happy to see him posting here - I've found the information he's presented to be quite valuable.
