Mills 35 Loop Cartridge Belt - Real or Repro?

[Big Al]

According to the table in my Mills catalog reprint, the loops of that belt are sized for the .38-55 cartridge. The .30-40 Krag isn't listed in the table, as that catalog likely predates the availability of that cartridge. Though, numbers 25 through 30 are unassigned. It was likely given one of those numbers in later editions.
