Replacement Parts for Revell American from the UK

I bought a model while on holiday in america, but it is missing a piece, how do I get a replacement for this piece within the UK? I have searched but found nothing.

Thanks

Chris

My suggestion is to post in the classifieds asking for the piece you're missing.

Revell USA doesn't ship missing parts outside the USA, so regardless of where you purchased the kit, you're stuck.
