I have some Penn 4/0s like your's. I bought them on ebay along with others. I try to get those that look unused for a low price; its amazing how many you can find that appear to never have been loaded, and if they have, they have had extremely good care and/or little use. I think a lot of the old red 4/0s were built in the 70's. They look great and work the same, even though they are vintage.
