I now have the complete First Rank to hand. The magazine ran for seven volumes to June 1984. While I am still missing one of my ring binders, I do have a number of spare copies, but was still missing three issues. Fortunately, Terry Whitton had retained all his copies so has been able to supply the three missing issues, so all will be complete.
Latest issues published: Volume 3 Issues 7 and 8.
