Most theaters moved to digital around 10 years ago and most of them got rid of their 35mm projectors (some kept one or two just in case)(I worked on the provider side of the migration to digital cinema at the time). In theory there should be an abundance of cheap 35mm projectors on the market, but maybe the demand wasn’t all that so most of the projectors were just tossed? I know some projectors were shipped to 3rd world countries as well.
