Borel Material Balance Staff for Hamilton 18s, SR, LC, P10, No. 127 / 607013 - New

Borel Material Balance Staff for 18s Hamilton, Single Roller, Large Collet, Pivot 10, Factory No 127 (607013), Refill #4, new in package.  See images for further details. Borel does a crappy job of marking their packages with data so double check the specs before buying. I specialize in hard to find parts and are sold with an unconditional guarantee.  Images do an adequate job of representing the item.
