This particular singletree is embossed LOUDEN MACHY CO. FAIRFIELD IA and was manufactured anywhere between the years 1870 -1887 before Louden applied and received his patents. Measurements are 26-1/4" wide at the opening, 20" from opening to O ring and the wood is 3 thick. Condition wise the cast iron stirrup and o rings are lightly rusted but move freely.Condition wise there are areas of rust, chips to the wood here and there and a thin linear surface split in the wood. The split is on the surface, is cosmetic and no stress weakness is noted. This item is barn picked so it still has some residual dirt. Please see photos for more details.
