1950’s Monark Skyliner

New to the site want to say hi to everyone I got this bike in a trade. 50s Monark Skyliner need info what year? It has a horn which is missing and a working headlight. The bike has the wrong pedals, and color of the seat, which should be green. I may have the wrong truss rods as well. I really fell for this bike. I collect Schwinn bikes but things are changing. Also the rear reflector and housing are mia. Any help would be great, what a great site. thanks Brad
