Help in identifying small caliber shells

[homebre]

I found these shells yesterday in Chapel Hill, NC and can't find any info. on the type, year, etc. I think they are 22 caliber rimless. The bottom has a circle with a Capital M over a Capital W inside the circle. Thanks for any help,

The look to be .22 Shorts or CB Caps (same rimfire case).

The manufacturer is Federal but sold by Montgomery Ward.

Thanks-any idea of the year?

Early 1930's to end of the 1950's is when they were made. Used . . . anytime after they were made up to now (I'm still shooting some 1960's stuff in my .22).
