M1 Heat Stamp dating for two helmets.

[MilitariaOne]

Greetings all,

Below are two helmets' heat stamp numbers. The top one is a front seamed helmet and the bottom one is rear seamed. I was wondering if either helmet falls into a specific date range based on these numbers? Thank you, for your assistance.

Regards,

Lance

Greetings Jake,

Thank you, for your response. It would appear that the lower helmet's heat stamp may be incomplete. This is what another forum had to say Two M1 Helmets' Heat Stamps (Date range?) - STEEL AND KEVLAR HELMETS - U.S. Militaria Forum
