They definitely started at "1" again each time they changed the design, I've seen type 1's with serial numbers in the 700 range, type 2 n?s 57-2800+, and a type 3 n?2. Now, to know if they were replacements that is hard say, I've no idea. On the other hand there were approx 3000 type 2 awarded and they are fairly common, but there were approx 2500 Red Banner for Military Valor Orders awarded which are MUCH, MUCH rarer. Their design changed more drastically also. So maybe these were exchanged and Polar stars not. Remember I do not know, I'm just thinking aloud So to quote Rick: We need documented Orders Book and awards SETS SETS SETS Jan
