It's hard to say if it's a Manhattan without seeing the VIN. The fact that there is no 'Manhattan' badge on the fender is an indicator that it is not. The narrow rocker molding is not a sure telltale nor is the beltline molding that's present. The '49/'50 Frazer is a strange animal. I've posted pictures of the '49 Manhattan that we restored several times before. It was F496-00xxxx indicating it was indeed a Manhattan. It also had Manhattan trim inside - color coordinated steering wheel, shift lever, signal light lever, chrome strips on all four door panels, chrome skirt on the bottom of the dash, chrome interior window frames etc. but it had the narrow rocker chrome and no belt line molding and appeared it never did.
