We would like to acquire for the Barre (Mass.) Historical Society a Diamond mower knife grinder as shown in this photo. It was manufactured by Chas. G. Allen Co., Barre, Mass., and sold to Whitman & Barnes Mfg. Co. by the thousands for resale nationwide and internationally. The grinder was sold from 1902 into the 1920s. It was also sold locally as the Yankee mowing machine knife grinder.
As far as we know, there is no name or patent date on it, but there may be part numbers cast into some of the castings. Perhaps one of your readers can help us locate this piece.
Charlie Allen, PO Box 488, Barre, MA 01005; phone (978) 355-4823
