Hi @impersonal, I appreciate the invitation.
It called my attention the name of monkey cap you mention, here in Venezuela they call it cap, it is mainly used to protect from the cold in children and adults.
A gift that for sure you will always take care of, and even someday you will give it to your children, a cherished memory of your grandfather.
I wish you luck in the challenge, best wishes!
Thank you for visiting my post and observations.
