Still trying to figure out how you got to “5 or 6”.
John,
If my math is correct, these and the three Christmas Party photos make six.
http://www.prayer-man.com/tsbd/gloria-calvery/I submit that your erstwhile "Glasses Woman" in Betzner-3 makes "7", no matter how much one over-enlarges it to try to make them go away.
Questions for you:
Can you find the black-blouse and black-headscarf-wearing woman (whom you labeled "Glasses Woman" until you realized Gloria Calvery wore glasses) in full-frame Betzner-3, below?
https://www.jfkassassinationgallery.com/displayimage.php?pid=1267&fullsize=1 Can you see Abraham Zapruder standing on the pedestal, behind her and a little to her left? (Do you need "proof" that that's really Abraham Zapruder up there, and/or that the photo was taken by Hugh Betzner?) When you look at Zapruder frames, can you find Hugh Betzner in the background? If not, can you figure out where he was standing by looking at full-frame Betzner-3, itself, or by looking at other photos and films that were taken simultaneously with Betzner-3?
Is the big, tall, black-blouse and black-headscarf-wearing woman in the Zapruder film standing a little to the left (and in the foreground, of course) of Hugh Betzner in Zapruder? Is the black-blouse and black-headscarf-wearing woman in Betzner-3 standing a little to the right (and in front of, of course) of Abraham Zapruder in Betzner-3? Don't you think that, taking these photographic observations into consideration, it's clear to open-minded students of the assassination that your black-blouse and black-headscarf-wearing "Glasses Woman" in Betzner-3 is the same person as the big, tall, black-blouse and black-headscarf-wearing woman in Zapruder?

PS Forum member Denis Morissette claims to have spotted Hugh Betzner (and Phil Willis!) in the Zapruder film:
