Either of the options mentioned above, but it definitely isn't one of ours.
It looks to be a flight of fancy carried out on what could possibly have been a UK military chassis going by the front bumpers. The rear cross member and assorted fittings, the tail light grouping, the fanciful cutting of the guards, as well as the lack of left fuel tank, to name but a few of the more obvious discrepancies stand out, but are just a few of the many missing mods that were applied to the original Landy products to make them at all acceptable for our military needs.
I must admit though, the colour is pretty close.
