Original U.S. WWI Era David Instrument Mfg. Co. Blaster No. 1 with Strap & Handle

Original Item. Only One Available. This is a very interesting blasting machine by Davis Instrument Mfg. Co. in Baltimore, Maryland during the World War I era. The machine is marked on the bottom as:

DAVIS-BLASTER
NO. 1
SERIAL 4193

The blaster retains its original leather strap which is weak, and the original crank handle which is attached via a chain and clasp. Interestingly, the handle is to be inserted into the bottom of the blaster to turn and activate it, a strange design choice. The entire machine measures roughly 4½ x 4 x 2”.

This blasting machine was meant mostly for coal mining, as similar examples have been found in old mines.

A great early 20th century blasting machine, ready for further research and display.
