I have two different Lima neon signs. One comes from the first half of the 60's (yellow box era) and shows a FS E.424 and Pullman Coach.
The second sign is apparently from 1983 (picture same as the 1983 general catalogue).
Unfortunately, both are currently not in working order. Maybe only the neon tubes are burnt out, but the plastic of the signs got old and breaks easily. Despite this, nice to watch anyway .
