I came across this a few days ago, from 5722 (1962 למספרם), video from the Brooklyn, NY levaya.
One sees several רבנים being מספיד. The first is Rav Avraham Kalmanovitz זצ"ל. Second is Rav Aharon Kotler זצ"ל I would guess (compare the images with a video from the same period featured here in the past). Third Rav Moshe Feinstein (?). Somewhat difficult to make out.
