It is indeed a 10S669, 1942 model. This was my first old radio, mine had a bad output transformer and I replaced all the rubber wiring. Yours is an early version as it has the gold dial pointer and gold painted speaker. The later models had a cream plastic "Neptune" dial pointer and a cad speaker as mine has:
