• Ref: NUMDA/3/2/42 — Mainsforth lodge subscription registers [1955-1973]
  The subscription registers record payments by members to national, district and local funds, with space to record exemptions from national and DMA political levy. Many registers list members alphabetically by surname with some indication of status (full member, half-member, widow etc), but this was not always possible because of changes in the workforce. Some registers include brief information on death, transfer, leaving mining.
