On the side of the trailer or some where should be a little metal tag that has a serial number, etc. If you can find that post the information, usually folks can research that pretty quickly. If you don't find a little tag, sticker, or some other identification ~ you might look on the tongue of the trailer. In the 1960s... they scribed the serial number in the tongue on the top. One has to look carefully to see it, if the tongue has been painted it often is hard to see. However, I don't know if they did that for the 1959's or not, as we have a 1955
and the number does not appear on the tongue.
You should restore or at least refurbish your trailer and go camping! They are great!
