Last year I bought this 1948 teardrop.
When asked "How old is it?" I reply, "only one year younger than I am, but the trailer is in much better shape."

There is no official provenance, but the details of how the trailer is built and many of the features are consistent with a trailer of that era, so I'm willing to accept "1948" as the year of origin. I love the oldness, but am almost finished renovating the interior with modern lighting, insulation, and hull liner wall covering.
