Nice one. Don't always assume it is a "world" model from the decals because up until '54 the decals didn't reflect the model name. Until that time they all (world traveler, world and world varsity) said "WORLD" on the seat and down tube decals. In '54 the down tube decals stated the name of the model. The seat tube decal still said world (confusing - I can go into all the decal transitions if needed).
1950 checks out on the SN. There are some other clues like the new world head badge that was used on '50/'51 travelers and world models. It also has the early stem found on travelers up to '53 (I think, then they changed to another style in '54). Pedals and saddle are incorrect. Pretty sure those bars are incorrect as they would not be torrington on there. But if this is a 1950, I guess there is a chance it could be original to the bike (maybe). I typically see the gull wing bars that are found on all the lightweight tourists of the 1950s. It would have also come with the black oval grips.
The "world" model give away is the painted fenders with striping and color blocking (if original paint...).
It looks like the paint was tweaked over time though... Or what am I seeing? It looks like it was sprayed blue over the original paint. The bottom bracket cups would not have had blue overspray on the edges as shown in the photo. But then it looks like it has maroon over that... What paint color is original?
You should really try an OA bath on this. I think you'd be surprised at the results. What have you got to lose...
