The second 'D' in the model code was normally the one ton designation. US civilian trucks were TD, VD, and WD for 1939, 1940, and 1941-up respectively.

The US TC, VC, and WC CIVILIAN trucks had light suspension all round. They upped the suspension rating on the rear a little for TD 15, VD 15 and WD 15 hybrid 15 cwt trucks, and went for heavier rear ends and different rear axle types for the proper TD 20 and TD 21 one ton trucks, though the front suspension and steering stayed the same.

The 1941 US one ton truck had a different axle and wheel type, so that image definitely isn't a WD 20 or WD 21. My best guess is that it represents all the remaining production of the 1939 and 1940 type six lug disc wheel axles stuck under very early 1941 production bodies (basically September 1940 on) because of the front sheetmetal configuration.

In the US the one ton truck was available as a 120 or 133 inch wheelbase pickup, but the panel van was only available as a 116" half ton or 133" one ton, i.e there was no 120" one ton panel van.
