Here's a video of your set being built. https://www.youtube.com/watch?v=kanPsUDyKrU
You may have seen it as it's made the phorums a number of times.
I'll mention a few things about it. The opening at :58 was "borrowed" from a radio series called Behind The Mike. Circa 1939-40. Good series for learning radio show production and enjoyable to listen to.
If you want to cut to the chase you can start the chassis being made at 10:32 and what you just got though ripping out at 12:00. Later on comes the cabinet. Wow they spray the lacquer heavy.
Sure looks like an 87 chassis!

Enjoy if you haven't seen it before.
