Happy Landing is 4 pages so it would be from 9, 10, 11, 13 or 17.
Master key is 7 pages so it would be from 11 or 13.
Punch and Cutey looks like 7 pages and another page from another story which would make it from 10-14 or 17, there is no 8 page story listed.
Looking at the site, Master Key from 13 is on site, so it probably is from 11.

Crime on the Run also appears in Snap Comics #9 (unscanned)
Gay Desperado also appears in Red Seal #14, 15, 16, 17, 18 and 20 at 6 pages. 16-18 and 20 the story is unscanned so it could possibly be from one of these.
