It's really a model 30A-99ar "Plant "S" ... or so it says inside.
I found the schematic under Sentinel so I think that's the real manufacturer.
After cleaning the metal chassis and sealing it under lacquer I also had to re-cone the speaker and completely re-build all the electronics.
I had this thing "mostly" done and sitting on my bench here for many months ... but only because I allowed myself to drift into many other projects over the last year or so.
But I was recently urged to re-light a fire under my butt and "get crackin"...
The only thing I had left to do was the cabinet. I certainly didn't want to be trying to work on it in my garage over the freezing winter months... but now with Spring here I had little excuse.
Since I hate spraying lacquer and messing up my garage with all that over-spray.. So, I decided to top-coat this one with a brush on Alkyd-Varnish.
I striped it with 50/50 lacquer-thinner/acetone.
The old finish just drips right off while I use a 00 steel wool pad to apply the liquid and then, while wet, wipe it off with paper towels.
I was pleasantly surprised after stripping how beautiful the wood was... especially the front face wood.
So I lucked out.
I tried to apply some Minwax "Gun-stock" stain... but it really didn't do anything as the wood was beautiful enough as it is.
So I just masked-off and sprayed the black trim using Black lacquer.
When dry I wiped everything down and applied one average to heavy coat of Alkyd-Varnish.
After dry I rubbed it out using a gray 3M pad followed by a green pad.
Here and there I used 0000 steel wool and final buffing with a soft cloth.
I later applied a light coat of spray wax as a final-finish.
I would normally have used a paste wax but didn't want to get any residue in the grooves of the trim.
Anyway, nice radio! Looks pretty good! Looks like the top, however, was originally 'colored', possibly to match the front, as it seems to be made of a wood that doesn't absorb color like the front.
