Dapol N Gauge Signals.

 First chance to see one of these as produced by Dapol.
It seems to scale out at about 18ft in height in 3mm-and works by simple flick switch. The lamp even works!
Nigel spent most of the October meeting playing and it seems about right for a 3mm layout- there are plans afoot to add this one to Nigel's layout St Leven which will be at the Poole MRE in November.
At a little over £20 locally, you would be hard pressed to make signals for that !
