So did S. Bougnet work for ML, sub work from them or did ML make scatter guns for S. Bougnet? I would lean toward the possibility that ML just made more examples that wears load data in either GR(Grammes) or ounces in that 1897 - 1903 period than most others. But I'll search for other ML examples from the period.

Also there seems to be a mixing of units. Dram and Dram Eq. do not have the same units. Dram is mass, Dram Eq. is more akin to velocity. Typically cartridge manufacturers either advertise velocity or Dram Eq., but not both.

Kind Regards,
