Ok I got this from militarymonark. Its a Westfield but dont know what year. The tubes in the back at the seat post are 1 1/2 inches apart. The ones on the 41 Westfield ar 1 inch apart...Tank I have just almost fits.pooie. Not quiet finished with my Hawthorne build ..but this one peaked my intrest. I wanted a lime green bike and I guess here it is....so far. Have most of the stuff to do this one with old parts...good skiptooth chain . Had the crank and sprocket powdercoated so I'm moving right along. it has a differant headbadge that has a big eagle and the screws are on the side instead of the top like the 41. Anybody got any ideas???
