I would guess that they were cartridges reloaded by a commercial loader back in the day.

In the early years, especially out here in the west, the ammunition companies shipped NPEs and local concerns loaded the shells. The largest and most often noted was Selby and California Powder Works (CPW)in California. We had Honeyman Hardware in Portland, Oregon; Miller Bros. in Tacoma, Washington; Piper & Taft and Hardy Hall in Seattle, Washington; and Ware Bros. here in Spokane, Washington --
