Hi WRENNEIRE.
In truth, I don't know if I still have the boxes, I doubt it, I would need to search the attic where I store the boxes of my rolling stock and locos. I have retained all boxes for the past 35 years, but before that it's a bit hit an miss. I will consider your advice about retaining them 'as is'. I have been considering either making or buying some display cases to retire stock for static display on track that I don't intend to run or run again (e.g. old Dublo, Triang, early Hornby locos that just don't run well and won't lend themselves to DCC conversion). These Limas and a lot of my old plastic wheeled hornby goods wagons may be candidates for static display.
Cheers
Noel
