War Department 16” divided rim: British and Canadian manufacture
The British War Department split rim came in various sizes. The one we look at here is the 6.00x16 version as fitted to Commonwealth 15- and 30-cwt trucks.
The rim width is 6" and the wheel diameter is 16", hence the 6.00x16 designation. It was also referred to as "flat base rim". This type of wheel was fitted with tyres sizes 9.00-16, 9.25-16 or 10.50-16, either in R.F. (Run Flat) or Pneumatic version. There were some variations between British and Canadian manufacture as explained in this thread. Please add more info if you can.

British made rim
British made rims have the valve stem opening to the right of the bolt. All eight bolts are the same length.
The example is marked "RF" and "6.00x16". It was made by Sankey and is dated "7/41". IMG_E5918_resized.jpg IMG_E5919_resized.jpg IMG_E5921_resized.jpg IMG_E5922_resized.jpg

Canadian made rim
Canadian made rims have the valve stem opening to the left of the bolt. Two of the eight bolts are longer than the other six.
This example has no maker or date stamp, only "6.00 / 16". IMG_E5925_resized.jpg IMG_E5926_resized.jpg IMG_E5927_resized.jpg IMG_5936_resized.jpg IMG_E5928_resized.jpg

Wheel diameter
As per the thread new 9.00-16 tyres for WD split rim wheels, Mike Kelly measured up some tyres and found out that the wheel diameter of the British/Canadian 16" tyres and rims are ¼" larger than those of US 16" tires and rims. That is why standard 9.00-16 tyres which are not marked "for British rim" can be hard to fit to this type of rim.
I measured the circumference at the bead at 129 cm which converts to a wheel diameter of 16,2 inch. The circumference of the British and Canadian made rims is the same. Wheel rim dimensions.gif

My Canadian rims have the attached instruction plate welded to them. Not present on my British rims (but they could have corroded away, of course).

Not meaning to divert this thread, those cuts can be repaired to present a better finished rim before final painting. While naturally a bead of weld will fill the grooves, the weld itself will require further grinding to clean it up flush and present a smooth lug nut seat. Some people might also have qualms about heat damage from the weld affecting the temper of the rim, and therefore it's structural soundness. I have had great success with a metal filling epoxy called JB Weld. It can be shaped, sanded, or ground easily and binds securely to metal, so won't fall off in a slab years later. Readily painted with any automotive primer and paint system (ie Enamel or Acrylic). It doesn't just work on repairing grind marks, it also does a fantastic job on sandblasted rims that have hollows from rust pitting or gouges from kerb strikes. You'll have that rim looking like new again.

Some similar info in THIS THREAD from 2006.
For reference, it should be stated that the thread on the studs is 7/8" BSF (7/8"-11tpi). All threads for the divided rim studs are right hand thread. On Canadian CMPs, wheels fitted to either left or right side of the vehicle have Left or Right hand thread 5/8" UNF (5/8"-18tpi) Lug Nut and Studs for each side of the vehicle. British vehicles that use these style of wheels (and also towed equipment like 25Pdr Guns and No27 Limbers, even those made in Canada) have BSF thread Lug Nuts and Studs in LH and RH 1n 5/8"BSF (5/8"-14tpi). These wheels freely interchange between Cdn or UK vehicles (and towed equipment), but the lug nuts and studs are particular to the vehicle.
