FSM only publishes 10 issues annually. The other two issues are the Annual "Great Scale Modelling" Yearbook, and probably some other hint'n'tip book. I dont know why only 10 issues out of 12-months, but June & some other month (August ??) are left out. There was a recent topic in the Off-Topic Forum (I think) titled "Why 10 issues of FSM" (I think - you can do a search if your keen) discussing this. Naturally, I didnt read it, because if I did, I could tell you the answer!
