Hi,
Nice selection of badges there Harry!
Your first two are from 1960s-70s era for "Instructor Parachutist" and "Instructor".
Here are my badges and para related documents + half-military organisation DOSAAF parachute documents (all belonged to one man).
Actually I am thinking to sell the badges as a one lot (expect one badge, that belongs with the docs).
Few photos as well (owner of the docs):
