Antique Vintage Jackhammer - 1920's Cochise Jack Hammer,,Hard Rock - Gold Mining, Authentic , Functional , Vintage, Collector, Collectible, Museum Grade

This antique Jack Hammer IS ALMOST ONE HUNDRED YEARS OLD !

It was recovered from a Northern California Gold Mine near Historic Gold Rush town Columbia and tested/working in the 1990's when hooked to a pneumatic compressor.

This is a similar year & engineering/design model to the one you see in the July 1933 Engineering & Mining Journal advertising flyer.

The one in the flyer is a Rock Drill, the one for sale here on Ebay is a Jack Hammer.

It comes with one genuine hexagonal jack hammer bit fitted with an internal water channel to keep dust from forming while hammering quartz, granite or other hard rock.

The Jack Hammer listed here for sale comes with a handle so that it can be better, more efficiently used with both hands instead of just one hand; the metal bar fitted to be used with both hands can be easily unscrewed & removed .

This is a very rare collectible tool , part of the California Gold Mining History.
