Kyosho Big Brute Parts (BIG-1/HRD-1) NIP

NIP BIG-1/HRD-1

This is what appears to be the gearbox case and bulkhead for a vintage Kyosho Big Brute and/or maybe Hi Rider?

Parts are still new in their bag but the bag is quite tatty due to years of storage. Must have purchased this in error many moons ago as I've never owned a Kyosho truck.

No idea what this is worth so please make me an offer.

Postage will be approx £4
