What have I got here? It has "Lindsay" embossed on the top of the handle. There's no fitting that I can see for attaching an air hose, but the cylinder is spring loaded. Is this one of Lindsay's early air graver handles? Or what?
you might get a more accurate answer by contacting steve lindsay. he would surely know about this. i use linsay tools and others as well. i have no clue what this might be.
