This is a very early vintage Singer Sewing Machine Model #66 and #99 complete original thread tension assembly. This style was used before Singer went to the more familiar tension indicator dial. This unit is in very nice clean condition and ready to go right on your machine. Might require some tension adjusting to operate properly on your machine. If your unit is giving you trouble, this one is a perfect original replacement.

Get Grandma's old baby back in operating condition with an early tension assembly. This will keep your machine in original condition.
