Post Type Twist Drill Question

I have a very old twist drill for steel, 1 and 23/32 inches in diameter. On two inches of length, the shank is a tapered square 7/8 to 1/2 inch
and no center support on the end face like to use with a tailstock dead center. The shank is too big for any of my brace and bit type hand braces or even my old, post drill press. - I was wondering if anybody could/would elaborate on it. - I figure it was originally for blacksmithing work. But I was also wondering before Jacobs or the currently typical various sizes tapered tanged shanks, was there a female mating tapered square type chuck to mate the drill shank? - "Whitman" is the name on the logo. - Wife's grandfather was a machinist, WW I vet era and I found a few big drills like this in his collection probably jury rigged for lathe work. - This drill must have fit an even bigger post drill press chuck than what I have. I was thinking of turning the shank down concentric to use in a Jacobs chuck, but it is too big of a diameter for my 4 jaw chuck through its body, unless I bore out the chuck. - Thanks for any replies, - -+- Kurt

Two possible uses:
1. with the tang pressed into the anvil, work can be turned upon it. Large work. 2. In blacksmithing, wagons and the like were built. They used braces without chucks. Metal ones anyway. They were wood and had a round tang and a square just before the 'barrel' that the drill fit into. This would be put into a brace handle or like tool - and then when seated a wedge holds it in. 3. A post drill drill bit maybe ?

I wonder if it is old enough that the steel is HSS. If it isn't, maybe you could just keep it as a keep sake.
