There was an attempt to nationalize number plate size and layout in the early 1950's. Each state was issued a range of letters . NSW: AAA to FZZ VIC: GAA to LZZ etc. Little Tassie only got a single prefix letter ... I think it was WAA . QLD was N to P or similar . Interesting is, Tassie was the first to 'go it alone' with a two letter - 4 numeral plate, I think it was in the late 1960's, . During the 1950's , I believe Tassie also had a clip on tag on the number plate for annual reg. payment rather than a windscreen decal , the tag displayed the year.
Thanks for all the info on the impressed vehicle methods ... I had a look at a 1941 Willys sedan years ago ( with GMH body I think ) up at Bendigo. The car was registered new to a Doctor in 1943 - the owners papers in the glovebox still. Quite a rare car . I wonder what beacme of it ..probably hot rodded
