You're perfectly right about the headlights, and I read that they were changed for 1920. So this can only be a 1920 or 1921. Now, on another well-known forum, the car below (in an Harold Lloyd short) has beeen identified as a 1921 Series V Touring Victoria. It looks perfectly similar, and these are the only two ones withs those lines that I found. Now I am a bit lost regarding the V3, V4, V5...
What do you think? The point is yours anyway.
Now there is another one at stake for finding why this bizarre paint scheme...
