This is the Very Rare Wrenn W6004.A "Brighton Belle" Intermediate Car, in Blue/Grey  only supplied out of the Wrenn, Basildon factory in 1992 before closure. I believe less than 50 were issued. This has the "S302S" running number not the more common S280S/S287S or S284S. These all match with the Wrenn W3004/5 standard  and W3004/5A Limited Edition Sets.

It was  often assumed that only 3 Centre Cars were available from Wrenn, Basildon, however I believe it was 4.

Comes complete it Period 4 1992 issued box with yellow cardboard insert.

Condition is "near mint to mint" considering age.
