I have the 1970's Lizzy with smoke and sound (my 2nd ever loco as a 3 or 4 year old), proudly in the display case beneath the layout.
Also the early 2000's variant which is lovely.
Just received the latest rendition, what a thing of beauty. Duly run in on the rolling road and now fitted (dare I say) with TTS decoder. So in the best part of 50 year things have come round from 'smoke and sound' to 'flickering firebox and sound'!
