I'm looking for 20 to 30 feet of some WW II coax. It's US Navy type CASSF-50-1. All I really know is that the OD is 0.410. Even better would be some made-up cables with Amphenol 80-81 coax connectors on the end. Please contact me off-list if you've got something. Even specs on the cable would be helpful. Thanks, -John
