This was bought from eBay in April 2012 for just shy of £100. Which considering the condition, age and that everything came with it (except the box) this was a steal. It is the early grey base, blue cylinder type with the old SV/whistle. A very unusual feature on this engine the boiler sight glass is convexed (unable to tell you why rollover the picture to see). Which makes this even more special to me.
