A neighbor said he had a NOS radiator for my 1951 truck. It is an earlier radiator with 46 in raised numbers - also 3112130 appears. The inlet and return pipes are cast iron - not brass tubing. Upper is turned down - lower is turned up. Would this be an Art Deco radiator? It is copper except for the fittings. Pics are posted in old chevy group at ya---oo.com groups. Would like to identify this original piece. Found in a parts warehouse. Thanks, BW
