[fv1620]

Yes it did but it is not all that it seems. Looks like a FV1604, but

This has a winch, FV1604 did not
This has a single speed gen, FV1604 had 2-speed
Reg starts with 1, FV1604 were late in the run & start with 3
The engine no. does match my records for the 1... reg no. & confirms it to be a FV1601.
Unfortunately the chassis plate is missing.

So body would seem to a later addition.

Having said that I am pleased to see a Humber preserved even if it was a conversion to a breakdown truck or something as long as in the future nobody buys thinking it is a FV1604.
