For starters, Land-Rover parts books read that the 1-Tons were always fitted with 569204 rims, also known as IIA FC rims. These are 6.5" rims but with the "lesser" offset. Generally speaking, most 1-Tons and TACR-1s do have 204 rims.
569204 rims:
The original rims from 26600082B were 204s for example.
However, some 1-Tons do appear to have genuine 569203 rims, such as 22900042G:
As this was a working breakdown truck all its life, and never in the hands of an enthusiast until it was bought by Nick, we can say with some certainty that they are the original rims.
My own vehicle also has a set of 203s, however they are not original to it, as the paint was originally deep bronze green. I doubt they are from an FC, and one of the previous owners had three 1-Tons including mine, so I would guess the rims are from one of his, I suspect vehicle 22900135H which I am fairly sure has the bonnet off mine!
As 569203 and 569204 are consecutive part numbers, it would be logical to suggest they were designed at the same time and probably (in fact almost certainly) made alongside each other. It would also make sense that the rims could have found their way under various vehicles - we know that Land-Rover could and did use whatever was to hand to complete a vehicle and get it out and sold, usually relating to items such as lamps, but perhaps also applicable to rims.
To add further confusion though, we do encounter rims which are stamped up 569203 which is then obliterated with XXXXX over the top, and re-stamped 569204. The rims physically *are* 569204s. There does seem to be some variation, with slightly different rims wearing the same part number.
Over to you then folks, what do you have? Any photos or measurements I am sure will be very useful.
