We are going to need a lot more pictures. The seat should be attached at the front. The rear fender is not mounted correctly. The front fender braces are 1949 or earlier, I believe.
It looks like the bike had a pull start on it, as I see a rope hanging from the handlebars. The kick start pinion gear is missing, as is the kick starter. I can't see it good enough, but it looks like the spark plugs and wiring is missing.
Don't be discouraged by my above comments, I think that bike has a lot of potential!
Post plenty of pictures and ask questions and we can help get you pointed in the correct direction.
