Bolt marking question
Was filling out m1 carbine data sheet today. Looking at the bolt it is a Winchester round. W on right lug (no hole on bottom). The question is on the bottom of the lug with the W is a 5 stamped? Can’t dind anything on this. Any insight would be appreciated. Thanks in advance

Marks have been reported in i believe starting 5 million range.
I beliebve the Carbine Club Newsletter on 5 mil block which mentions it

Just had time to check, 5 Mil block update does not specifically mention the numbers. 6 and 7 million update does mention it and believed to be inspection marks.
