I did mention the 121 class to Paddy back in August,and
He did say it will be a few years as He suggested the 071s
had taken a number of years to get to the production stage.
As regards the MIR version,I have a resin version with a
unpowered SW 1500 athearn underneath.
Gerry Byrne has a lovely collection of 121s that I must get
good photos of.I do remember a single 121 running nose first
at Edermine LC near Enniscorthy many years ago.I don't know
what the story was,perhaps a breakdown.
