The MRC 's Chiltern Green/Luton Hoo and the MMRS Gransmoor/Gransmoor Town both represent the previous generation of layout. Both had an N gauge roundy roundy with a 2mmFS branch.
Gransmoor had gone by the time I joined the MMRS but Gransmoor Town (the 2mmFS bit) was still out on the exhibition circuit (Blackburn, Nottingham, Hull, Rochdale amongst others) and was a delight to operate with Mike Raithby's superb Midland stock - I think we might have had Tim's Kirtley well tank on loan for a while.
Both clubs used the 2mmFS branch line add on as proof of concept that paved the way for the much more ambitious 2mmFS Chee Tor and Copenhagen Fields.
