Export's Junior Weekly Part I

On the back cover of Export's Top Action Western (titled Top Adventure on the back cover) there is an ad for a new periodical called Junior Weekly. The comic is undated.

How many issues were published before Export's business was ruined by the Decmber 11, 1950 fire? I know of three dated December 2, 9 and 16, 1950. There is mention of "junior weeklies" in the December 15, 1950 story about the fire in the local newspaper, The Advertiser. This is likely the third and final issue.
