Borel Material Balance Staff for Hamilton 16s, DR, LC, P10, No. 434 - New

Borel Material Balance Staff for 16s Hamilton, Double Roller, Large Collet (.98), Pivot 10, Factory No 434, 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.
