1915 - ish Implement & Tractor Trade Journal Advertising Page

This original page from a Implement & Tractor Trade Journal has been trimmed to @ 8 x 11" and features 2 Traction Engines that I believe are quite rare today.  The front side features the Flour City Tractor line of 4 kerosene tractors made for 3 to 10 plows, while the reverse side features the Reed tractor out of Kalamazoo, Michigan.  Other ads on the page include New Idea Spreaders, Webster Tri-Polar Oscillator and a one Pipe Furnace + others.   The page is not dated nor are any of the ads, so I'm estimating the date based on magazines of that time I know I have salvaged.
