Ray et al We see a lot of # 7s on this continent but not of the John Spear, Spear and Jackson variety. I can't think of this saw as being anything other than a reaction to the #one selling saw, the very popular Disston #7. Disston had been selling many fancier saws but the basic straight back basic beech handle saw was one of its earliest and longest made. Much has been written and studied about Disston saws including many catalogues with the #7 included. I don't think it is a coincidence that Spear and Jackson decided to include this single digit into their saw stable. It is unfortunate that we don't have any early catalogues to suggest a date these may have been sold but Simon suggests 1860. The numbering evolved in the later years to multiple digits as a designation of the type and quality. If someone does have an early catalogue I am sure we would love to see it. I am also wondering if this was an export saw and if there have been many found in Great Britain. I am sure someone can clarify that. This 28" straight back saw is in wonderful condition and I had absolutely no buyers regret when it was offered. The beech handle is virtually mint, the etch is very visible on a nice shiny well taken care of blade and the medallion proudly displays that #7. The metal in this blade was top notch. It also has the number 6 PPI stamped at the heal. I certainly wasn't sharpened a whole lot. enjoy Joe S.
