Ford’s digital UK archives have been added to the Ford Heritage Vault online historical database

The Ford online historical database containing thousands of Blue Oval photos and brochures was launched back in June 2022 and as Ford Authority reported earlier this week, Ford’s preservation efforts continue as the company just launched its brand new UK-based Heritage and Innovation Center, moving its collection of historic vehicles from Dagenham to Daventry.

Now, the automaker’s digital UK archives have also been added to the Ford Heritage Vault, giving those that can’t make the trip to the UK a chance to check out more than 1,600 new photos and brochures from FoMoCo vehicles based in that country.

The Australian database is prevented by some law from being accessed out of their country
