It might be worth listing the ones you are missing as from time to time the odd few turn up when having a clear out. That includes both club stock and individual members who might have spares. You never kn ow your luck.
I could do with a FAB 1 – any chance that this might appear as a special re-print, or as a PDF?
Also, what about making FAB available as a PDF to paid up members? I do realise the practicalities of producing these as PDFs, but at least some of the more recent magazines have surely been produced with layup/publishing software for the printer: any scope for at least these editions?
