I believe this is their model 1653LR/5038 combo case that will take barrels up to 34” with extended choke tubes. Black with dark blue interior. Case only used a few times and is about 95% plus condition. $325 shipped in CONUS.
From what I see the 1654 is for barrels up to 32” plus chokes, inside length is 34” This will handle up to 34” plus chokes, inside length is 36.25”. Both the website and their catalog indicate this is a 1653. Their description indicates the case is navy so I guess this case is navy but it is a very dark navy.
