There’s a 1904 Auto-5 for sale on Gunbroker. It’s listed as a 1927 and isn’t going for much. I put a small bid on it but if any of you guys want it I won’t bid any more. I’ve already got a 1903. https://www.gunbroker.com/item/890469223
Justin, you didn’t missed anything. I believe there is a lot of issues with that shotgun. It is good for parts only.
