[QUOTE=Peter J. According to you, a cross marked with a "5" and "21" is produced post-43. That´s correct, but what happened to the "900"?. You see my point [/QUOTE]
In 1943-1945, there were crosses of 5th category with markings "900 21" in the ring and "21" in the ring, and "5" at the fan. The two types of marking coexisted in that period.
There are also variants to this rule, such as orders of Eagle brands and transitional Eagle orders, manufactured with the design of 1939-1943 but with the ring marked "900 21" corresponding to 1943-1945. This is not a standard, in this case, simply the manufacturer added new rings to the parts they already had in stock to be delivered that were manufactured in 1939-1945...
