[Richard Coutts-Smith]

John, ARN's were not issued in order of chassis #, it was a case of next in line, so arriving at 105 691 via chassis counting would be an anomaly, in this case it was the 18th truck to be numbered, so good guess indeed.
Trucks were delivered in the factory finish, the British version of Deep Bronze Green, slightly different to the Aust. norm. This needs to be stressed when having paint mixed by the experts.... Many were over painted at some stage, but to my knowledge never in a Cammo. pattern.
It is has been remarked upon before how well the Humber bolts will come apart even after years of living outside, biggest exception is the tub floor bolts, shame you will miss out on them!
As Richard Farrant mentioned in a previous post, most Humber parts are unique, there was no off the shelf gearbox, transfer case, running gear parts. This design was part of a Grand Plan project that became so incredibly expensive it was shut down because Britain could not afford it, with only a handful of vehicles being finalised, now you know why.

Manuals are pretty ordinary, but you can't do without them.
Vintagemanuals.co.uk had copies made, there is a drivers handbook, spare parts cat, and a combined manual that covers Cargo, wireless and armoured.
