There are a few more Philco models which were made prior to WWII:

1940:
A52CK
A52CK1

1941:
41-KR

1942:
42-KR5
42-22CL

Model 41-22CL is a 1941 model. The 41-22CL and 42-22CL are identical, other than the slightly different model numbers as it was made for two model years.

And, yes, all of the above were just radios with clocks. They did not have alarms, buzzers, or the ability to wake you up or put you to sleep to music.
