Looking to buy Old Eyeglasses - $500

Hello, I am currently working on a film project set in the 1950s, and I need a substantial number of eyeglasses to ensure historical accuracy.
If you or anyone you know happens to have old eyeglasses from that era, I would be incredibly grateful for your assistance.
Specifically, We are seeking around 50 pairs (or more) of eyeglasses that fit the 1950s-1960s style.
If you can help in any way or provide leads, please feel free to reach out to me at your convenience.
We have a strong budget.
Thank you so much for considering my request.
Your support would be invaluable to our project.
Warm regards.
