Millers Falls adj. angle bit brace attachment

Went to a small swap meet/car show Sun., only thing of interest that I bought was this Millers Falls #108 bit brace attachment that allows you to change the angle, to get in tight spots I presume. Never saw or heard of one before, figured it would be rare, but apparently not that hard to come by, although the others I saw didn't seem in as good condition as this one.
Stopped at a flea market on the way home, found the GTD #6 tap wrench, didn't need it as I already have one, but it was too cheap to leave behind.

Nice find. I love those old brace & bit sets, but I've never seen an angle attachment like that. It looks like it's in pretty good shape too.

That angle bit brace is over the top way cool as they say...
