Help ID this vintage tool - Model T valve tool or ????

[Ed in Virginia]

I picked this up at an estate sale. It was in a box with a variety of flathead valve tools. I've never seen one like this and am hoping that the collective wisdom and experience at GJ can help me ID it. Thanks in advance for any help with it.

^ No problem.
Rather curious finding the "PAT PEND" notation in a 1923 catalog on an item for which the patent was issued in 1918.
