According to sources such as BSSM, W&P saws were factored, and with all these things the issue is always "by whom?" This example is very interesting because it backs up Simon's musings on factoring, such as Disston putting out No. 7s etched for Matheson & Sons, Glasgow. When I saw this example, I thought I've seen this before...US maker, deep style etch, cherry wood handle, open slot handle at the top, curved heel, lurid orange lacquer, the style of wheat carving... Fancy etch of a sailing ship. The most interesting part is right at the bottom, near the teeth. Yep, it says "made in U.S.A" The W&P is on the right, the saw on the left is a Simonds '72', which was a top shelf product at the time (ca. 1910-1920) and fitting of a high end tool company like W&P. Although not a dead ringer, the style of cut out alone makes me suspect that Simond's was the ultimate source of this saw.
