Hello. Are you still interested in purchasing a CH291 Battery box? I have one, with only one of the three 2v batteries in it. The battery is dated 4 of 1945. The box is around the same age as well. The box is in good condition for its age, with very minor surface rust. The 2 Comm ports used in this box, however, are not there. The actual plug is gone and it is just a hole in the box now. The O-Ring seal for the lid is flawless, and still seals great. The glass side pieces are not broken nor have they been replaced. If you are interested, please email me back. My email is richmccaig@yahoo.com Thanks.
