I think you’ve found a “smoking gun” here! I’m just catching up on all this after a good night’s sleep, but it appears from this and other evidence of the layering that the Australian BC is probably a fake.
Hey guys, the 10th with the old style of using the lower case L is different as was pointed out by wndawmn666, but look at the 1 in all the other areas as pointed out.
It’s EXACTLY the same one in the font I posted that the other letters are in, Office Memorandum AOE. The #1 is distinct in this font because it’s like a little upside L. You see how the top of the #1 goes straight to the left?
Look at post 6129 and see if you can see what I mean. This confirms to me that it IS the COMPUTER font of Office Memorandum AOE and not a typewriter.
