There is a hint in number 102 below, Charm is Every Woman's Business, that the publisher is connected to Export Publishing Enterprises Ltd. The book is as poorly produced as Export's average book and the author's name is "Claire" on the front cover and spine and "Clare" on the back cover and title page. This is an Export "mark of distinction".
Each book's copyright page announces "This book has been selected for reprint because of its popular appeal and its successful record of sale when originally printed. The story is exactly as represented in the synopsis on the following page…". Even the eight paperback originals have this announcement. I haven't checked any of the books with the original editions but this sounds like a sneaky way of suggesting that the Arrow edition just might be abridged.
Here are the first three books in the series. The books are dated November 1949 and 128 pages long. All cover art is by D. Rickard.
