I just purchased the subject stove as new off eBay on July 8, 2025. However, this vintage S-300, while new, is missing the propane hose. Seller didn’t notice it missing. I need to find a propane connection hose for it! Any help would be appreciated. Rick

The bottom photo w hose seems right to me. The upper photo is of the correct stove box. The questions and comments in the website are familiar to me also. I believe I had already been there. Here are photos of my stove and instruction manual.
