Look for a 1950's Kodak Brownie Hawkeye Flash. They can use currently available 120 film as long as you have an original 620 take-up spool.
A little searching can turn up an entire kit in the original box for little money. The camera might need a quick cleaning to get the lens cleared up. Lots of how-to's on the internet.
It would make a fun novelty gift and still produce great pictures.
