Cheers for that Gaz. I am the Shaun mentioned.
52lt monokey box, easily fits 2 helmets in, built in brake light (plate with brake light point required)
2 keys, although one is a bit rough, one is new and just recently cost me a fiver from ebay.
£95 posted for the box. I'd probably use a local 24hr courier who needs a signature on delivery. Pics attached.
£25 if you need the plate with the electrics point on.
