Hi, pardon the late reply due to travelling. Most of the letters numbers are fairly clear, but not all. First is definitely an 'A' followed by something that looks like a 'R' could also be the number 12 or possibly some version of a D maybe (but not likely), then followed by 3415 or possibly 3475. So my best guess is AR 3415 or A12 3415, with the slight possibility of the '1' being a '7'. Thanks Kevin for pointing that out, I should obviously have included that from the start.
