I see the post is quite old (2013), but I recently got the exact same radio from a garage sell. Same as yours no indication of model number or year of manufacturing. Have you ever got more info about this radio?... more pictures of my salvaged / found Granada radio ( forum allows 4 pictures max per post )
[ Looking at the schematic sticker on the bottom, looks like it has 8 transistors and 6 diodes. ]
I have carefully steamed and removed the schematic sticker on the bottom, and scanned it best I could,
but that file is pretty large and cannot be posted to the forum - I do not think.
The schematic scan came out not bad at say 600 dpi or 1200 dpi and medium or high sharpness enhanced.
Also ... steaming it sort of diluted / washed away the brown stain and made it all light brown - small sticker, but scan is readable.
I feel like I'm into some sort of "Radio ART / History PRESERVATION" or something.
