I've just had an email via EATES from PARC, a childrens charity based in Essex
On Sunday 11th September they are holding The Great British Vintage Fair at Braintree in Essex
http://www.thegreatbritishvintagefair.co.uk/
They are looking for old vehicles and engines if anyone is interested. Doesn't sound like its a costs covered job, more one for the fun of getting involved. They are hoping to raise £20,000 for the charity over the course of the days activities
If anyone is interested please let me know and I'll put you in touch
