it is a pdf and do not know how to pull images from pdf and put them into jpeg format

Screen grab and save to photo folder on a smartphone, or save as jpeg on a pc?

If this is not a BSA, does anyone know what makers had vertical headbadge rivets the same distance apart and serial numbers on the drop out?
Thanks!
