E. F. B & Co. Watchmakers Balance Truing Caliper

E. F. B & Co. Balance Truing Caliber, Made in France, in original box. The condition of the box and tool can be best described as "well used" and the tool could use a good clean and lubricate. The box is barely there, held together mostly by 50 year old scotch tape. I personally prefer this style over the K&D & Levin models that you screw to open and closed as these caliper style ones are much easier to manipulate, especially with small baguette balances. Images do a pretty good job of representing the item.
