Large aquarium with lids (North City NR3)

This is an all-glass (i.e. frameless) aquarium made by Sovereign Aquaria (a top make then) nearly 50 years ago. It no longer reliably holds water, though can be filled about half-full, and one of the corner lid-supports is missing. The aquarium is 54" long, 12.5" high and 18" wide. The leak could be repaired (I repaired the aquarium below it in my photo about 15 years ago), but as it is, this one would probably suit reptiles, plants, gerbils or maybe turtles rather than fishes. There are polystyrene tiles to go under the aquarium to take up any unevenness in the surface upon which it will stand. The lids are aluminium and have fittings for fluorescent lighting e.g. Grolux. It could all do with a good clean! I am replacing all three of my identical aquariums so shall offer the other two in due course
