Welcome! I build reproductions of the 1947 Kit Kamper and your trailer appears to be a “newer” made clone of that iconic teardrop. Many of the proportions are very similar, and although your galley layout has been simplified the cabin interior is true to the original. The fenders are modern but the A-frame tongue style as well as the axle spacing are much like the original ‘47 Kit. This trailer may have been built for only a short time which will make builder info hard to locate. It looks like there is lots of good trailer there. It should clean up nicely and be towable by just about any car. Have fun with it!
And just found this from 2001:
“Ron [Starheim of Seattle] builds teardrop trailers, modeled after a 1939 trailer Ron bought from a farmer. “
