I agree with the buggy shaft tip ID, but I have to disagree that the other object is a Hame tip... because Hames tips are curved, as shown in the horsegear catalog scan, and don't have a flange encirling the tube. The object appears to be brass and it has a flange encircling its tapered tubular body a little above the larger end. That matches up with Nhbenz's guess, a whiffletree-tip whose D-shaped loop missing. See the catalog-scan and photo below.
