Hello everyone, I just recently picked up this Adlake CNW lamp, was baffled as to what it was when I bought it, but after doing some research I found out that it's an old CNW semaphore lamp. Looks to be 100% original. So, my question is: can anyone help me figure out how old this may be and the time period it was used in. Any usage information would also be helpful and much appreciated. Any ideas on value? Thank you! -Andrew
