Incidentally, I also have a 105.003 from Germany with paperwork marked 145.003. Omega Archives confirmed it as 145.003, but they won't issue am extract with that as the 145.003 designation was an internal "logistics" number and not an actual reference number, so they told me.
The paperwork I have for my watch though shows both numbers, 105.003 and 145.003 in different colour inks . So, someone must have added one of them later. Personally, I think the 105.003 was added later.
Pic later if I can find the box .
