Hi,
Actually, that RCA is an 813K, one step down from an 816K. The giveaway for the 813K is that the speaker "fins" are slightly different and the bottom "feet", for lack of a better word, are black. The 816K fins are rounded on the ends while the 813K fins are not. The 816K feet are not black.
Do a Google search for 816K or 813K to see some restoration efforts. There's a lot going on underneath the chassis, but, on the good side, there's lots of room to work.
The 8= 1938, the 13= 13 tubes, the K= console.
That said, the 813K is considered by many to be a really good radio and well worth restoring. If you're new to the hobby and restoring radios I would recommend grabbing this radio and hanging on to it and restoring it later after your skills grow.
I would also recommend checking out Phil's Old Radios at
www.antiqueradio.org. Check out The Beginner's Section. On You Tube, I would also check out the radio restoration videos of joernone. His videos are geared specifically toward newbie's such as yourself. He'll start out with a real mess and make it into something wonderful!
Good luck, welcome to the hobby and welcome to the forum!
