Hello. Cool old bike. Looks like this Swallow. Your bike seems lacking of the duckbill front fender shown in the catalogue and the rear skirt guard. Picture is from a 33-34 fall/winter Sears catalog page taken from the Elgin, Higgins, Hawthorn Collectable Bikes book available online. Great resource. Not sure of the value of your bike but that's only really figured by what someone wants to pay for it. Keep it as is for now unless you plan on riding it. Any attempt at fixing it up may reduce it's value if you don't know what your doing.
