Not much to go on but you could look for ANY numbers printed
on any parts & post them here. Often you can ID a set just by
the part number system. Example almost all Sharp part ##'s
end with CEZZ, TAZZ, WRKO etc. Everyone has a different
scheme. Other than that it does have the Sony look but I
doubt its a Sony. IMHO another early 60's Jap set & since it has
a Toshiba jug very possibly by them but anyone else from JA
possible. Good luck & let us know what you find.
