Yes it looks like YVB 1xxH were the press cars and pre-production models.
YVB 153H seems to always have the by LR badge but YVB 151H (in some places referred to as Chassis #1, but I can't confirm) sometimes does and sometimes doesn't. YVB 150H which still has the Velar badge on the front has it as well but I can't get the pics.
I guess the point here is that LR couldn't make up their mind if it was a LR or not. For the first 3 years they put a badge on them pronouncing their heritage but then they took it off. They left it off until about the mid/late 80s and then it slowly crept back. Most of the LRNA models seem to have it but UK trucks of the same or later vintage don't always.
The last pic is interesting. It claims to be the 1st model of the RR. Or maybe a model of the 1st RR, it's not clear. It is based on YVB 151H supposedly. Anyway, it doesn't say LR on it. I am sure that it had to be approved by LR and the missing badge again questions LRs intent as to whether the RR is really a LR.
Now they can't decide if they want to split the company or not.
Seems like even LR over the space of its life couldn't decide if it's a 'real' Land Rover or not....
