Look up Unis, research institutes, anything electronic etc, in your area.
Hand write a letter (not emails) detailing that you are looking for an old scope for learning and becoming the best engineer you can in a few years. Add a picture of yourself soldering and some circuits you already have designed.

Should be 4 to 5 pages, well laid out and entertaining.
A bit of honest grovelling is always worth trying.
