Not sure of what year(s) these are but they are likely 1948-52. I have restored a number of "post war" autos since 1974. My specialty has always been Chrysler products. I currently am not actively involved in the vintage auto hobby but would like to resume some day. Like with everything else (insulators as well) the cost of pursuing these hobbies has become rather somewhat restraining to ordinary budgets like mine. But I look forward to reinvolvement with the vintage auto collector scene here in southeastern MA like I did some years ago.
