Since one of them has a date of 1983 on it and the style is identical, likely they have to have been done after 1983.
Maybe email or contact the museum with a scan and ask if they have further details.
I have just got 16 "labels" with various aircraft drawn on them and when I try to find out anything on the internet all I get is info about the museum and nothing about these labels, can anyone shed any light on them (e.g. year, how many different, etc).
Thank you for your time
