I have a little info I can add. D3541666 was made late 1909 to early 1910. The website dating info is not correct for this model. Sears referred to the model as Minnesota A9 on their needle packs but for conversation Davis New Minnesota A would be the best description. The A9 uses a 2" Davis long needle which is not standard so you'll have to find some on ebay or use a modern substitute needle called MTx190 or 190R. The A10 model is identical but used standard 15x1 rather than Davis long. Have fun.
