Nice to see a Humber that is loved & used. Fuel consumption not too bad really. The text book is 9mpg on normal roads, off road is not quoted which can be so variable I suppose. Look forward to seeing some more pics esp the chassis plate.
As for other FV1600s, I have:
FV1600 (beyond restoration)
FV1609 (restored & running)
FV1612 (restored but engine bust)
FV1620 (restored & running)
See what I mean about beyond restoration
