"Austin Champ split rims (set of 5) also for land rover series 1, 2 or 3"A rare find I would think.http://www.ebay.com.au/itm/Austin-Champ-split-rims-set-of-5-also-for-land-rover-series-1-2-or-3-/251490977219?pt=AU_Car_Parts_Accessories&hash=item3a8e07c5c3&_uhb=1
Not that rare but they are different to the type used on series 1s.That said you can make a reasonable facsimilie of the Series 1 type by using the Champ back/hub side and WWII Jeep outer rim. You can then sell the outer rim to Jeep owners who want wider rims.
