1984 Alvis Streaker Load Carrier (B481 RDU)
I believe this prototype aluminium tank is unique, having been built by Alvis, Coventry, England as a private venture.
I know that the UK MoD didn't purchase any and understand that there were no sales to overseas customers.
It's basically the front end of a Spartan but with no upper side plates and roof.
I understand it is now in private hands and it was seen at the Town and Country Festival, Stoneleigh, Warwickshire, England in August 1999.
