The Explorer had a tuning dial completely different from the other 888s, and this required a large aluminum plate anchored to the chassis — see chassis photo below.
This Emerson 888 Explorer was named after the first US satellite to be successfully launched into orbit, by the pre-NASA US Army Ballistic Missile Agency, on January 31, 1958.
