Re: What were IF code wheels used for?
Thomas, I am glad you said that because I have been saying there is an offset difference forever but I never thought about changes done over time and the date codes. You would have thought they would have used a different wheel codes if they changed the offsets. The first 2 pictures are of the IF wheel I had at the time and second 2 pictures are of the XT wheel I had at the time.
