Its in good conditon, the basic Astra 48ltr without extra lights etc, comes with 2 keys. Its fully waterproof, the metal rack is a universal one I've added (see photos, needed to use spacers at the rear, but very sturdy and very handy for a tent/camping chairs). The universal base plate can be bolted direct to the Wee rack or you could use the Givi adapter plates & bolt the Coocase plate to those I think.
I'm after around £60, would prefer collection, but if you can't do that the postage would be £15.50- Royal Mail insured.
Any questions/offers send me a pm
