The top one I reckon is a circa 1932...those bonnet/hood louvres are similar to the first Bedfords. I will have to check my books. However, the chrome rad grille surround is a GMC trademark, and I am now militating towards a 1932 GMC T-18.

The next one that I could have a go at is a late Twenties 4-cylinder I reckon, very similar to British buses of the period. The artillery-wheeled bus is possibly a 1928 Model Capitol Series LO, unless anyone can tell me it has front brakes ...in which case it,s a LP with 4-speed gearbox. Very similar to British buses of the time.

The 'another shot' appears to be a 1929 International Series LQ, by the small bonnet louvres but that rad grille just might be a GMC one.

Going back to the 6 x 4, a Danish company started up a 6 x 4 bogie conversion for Chevrolets in 1925, and this spawned several British conversions using an extra rear bogie. However I believe that in 1932 there was the first officially approved Chevrolet 6 x 4 conversion for use in say oil exploration, from THORNTON! Thornton of course used Timken components in later times..can I suggest a Thornton conversion as supplied by GM Java on either Chevrolet or GMC chassis?
