It's not a 1947 Willy's, nor is it a CJ2A. Looks more like a late 50 onwards model CJ3A.
The 49's had a body plate, different air filter and an indentation in the air pipe to allow for the radiator support stay.
CJ2A's - finished production in 48, they had a split screen, no cowl air vent etc.
The soft top supports are more MB than CJ3A, not original and the front bumper is also MB not CJ3A....the other thing that indicate that it is later than 50 is the steering conversion has a replacement dash, these are weld i unlike the MB's and M38's. Earlier model CJ3A's (i.e. 1949) had steering conversions but the dash remained the original left hand drive dash.
Needs better pics to tell more but if the wooden windscreen hood blocks are evenly spaced on the hood then it is no earlier than a 1950 model CJ3A, as the earlier hood blocks were not evenly spaced.
Other than those minor details she looks sweet and so far the price is very good, lets see what she goes for? Her tub is way better than the condition mine is in
