What is this little RCA tube tv?

[Sealtest]

Hey guys, what is this little set? The labels are either damaged or missing.

This little set took me by surprise. For the longest time I set it way back on my project list since it appeared to be a cheap RCA solid state set. Unfortunately a lot of my projects I'm stuck on so I pulled this thing out just for a break from the same sets. I noticed the back lacked the normal "no user serviceable parts inside" so I took it apart and found a very rough but cool tube chassis. Sadly it has those annoying RCA connections that are always broken so I'm not sure what to do about that.

So what is this thing? Any ideas about when it was made or if it is worth repairing? It is overall a very rough set.
