I found an 18" Martin backsaw last weekend. It came with a mitre box as a package deal, although it appears this is not an original pairing but only a marriage of convenience, and the only redeeming feature of the mitre box is its nice wingnut screws on the saw depth limiting brackets. What interested me about the saw was its new-to-me name of Martin, and Warranted Superior medallion withthe "George and the Dragon" motif Martin seems likely to be John Martin & Co, Wentworth Works, Wentworth St, who I found listed in various Sheffield directories from 1849-1862, generally as a steel manufacturer of files etc (only the 1862 entry seems to include mention of saws) HSMOB lists him as 1852-55 The George and the Dragon style medallion was also new to my collection [see also Joe's nice Pacey & Armitage saw, with THREE of these medallions, that he posted today] The types of English Warranted Superior medallions I have are this type and versions of Lion-and-Unicorn crests. [sorry about the picture quality, maybe someone else can post some better examples] Does anyone know if various WS medallions are specific to certain time periods ? or manufacturers ?
