Since I have not been out to get any new photos lately, I raided the "archives". I ended up with some GP40 photos, such as this: Harold
Harold, on the first photo, there is a yellow circle showing above the "st" in System. It looks as though it could be the "O" of B & O showing through, but I am not sure if it is quite in the right position?
Alan, I noticed the circle, and think you are correct! If you look hard, you can also see part of the "&" and "B" to the left. Good catch! Harold
