Thanks for all the replies, advice and comments

. Sorry not to have got back sooner but its been a bit hectic with my brother on a tight schedule.
My brothers wife forgot to arrange the International carrier....

my brother was not pleased , so in the end the safe( in a crate )is still in my workshop.
We went yesterday, I had the bikes on the trailer and all the other extra engines and fairings in the fronty completely filling it even with the back seats out and we took them to a lock up in Hampton.
I have a small forklift at my workshop which lifts about a ton so I can load it ok. I expect my brother will arrange something
It may be easier to get a van to take it.
Thanks for all the details on vin plates which I didn't know about.
Still tempted to try loading it in the back just to see

.
