HI,
I'd say mid to late 60s on this one. Is there any type of ID on the back cover. Or perhaps stamped on the circuit board?
The main issue with some of these is the circuit board may have been heat damaged by the rectifier and audio output tubes. It could range from just a discoloration, to lifting copper traces lifting.
What kind of info are you needing on it? If the set has not been messed with before, the replacement and ID of of parts should be easy.
I'd use a bristle brush (dollar store ' basting brush") to brush off the dirt and dust. If the cabinet has no paper labels, you can disassemble the chassis from it, then wash with some warm soap and water. Be careful of the paint in the numbers.
Here is another one I found, but there wasn't any ID with the text.

Do an inspection of the underside of the board and see if there are any breaks or solder joints that have cracks in them. You will see what I mean about the discoloration around the tube sockets.
Curious, have you powered the set up at all ? As this is not really a vintage set yet, you might be able to get away with powering it up for a few seconds.
You will either hear stations, or hear a hum. If it hums, remove power at once.
That's an indication that the filter caps have failed and need to be replaced.
If the set plays with no hum, it shows that all the circuits are working. I would still replace the filter caps at that point.
ALthough the set is 'newer' we are talking about 40 year old capacitors that could fail at any time.
I think that this is a great set if you are starting a collection, Philco too
Let us know how you come along and if you have any more questions, please ask.
