Now isn't this one pretty! I think it is a 1950. http://forum.toycarexchange.com/vb/showthread.php/50504-Plymouth?p=454940#post454940
Very nice. Top of the Plymouth line in 1950 - Called the 'Special Deluxe'.... Here's a page from the 1950 Plymouth brochure: http://www.lov2xlr8.no/brochures/plymouth/50plym/bilder/11.jpg
1949. I believe Plymouth never had a woody in '50 with '49 being the last year. But I could be wrong about the wood. The grill is indeed '49. Buick produced the last wood bodied station wagon in 1953. Ford converted to a steel in 1949 but used wood appliqués with decals till 50. Chevrolet had both a wood wagon and a steel wagon in 1950 but dropped the wood by '51. (or was it a year earlier, I get confused)
