Check out
www.wittern.com. Hawkeye Novelty morphed into Wittern. The attached pic came from their website. Also google "Hawkeye Novelty Co Billboard Popcorn" for a 1948 Billboard Magazine story about Hawkeye's introduction of its popcorn vendor. I believe the popcorn and peanut versions were mechanically identical, but I could be wrong.
Here are a few pics of a Hawkeye Popcorn Vendor I picked up a few years ago in North Dakota. I haven't touched it since I bought it. If you need measurements to have a chute made or any other help, let me know.
