Please help out ... I can't quite ID. I just got a cover, and the King George V 1p Green looked interesting, as I saw a dent on the bottom frame. My ACSC notes a variety called 82(1)d which shows a series of dents. Here is a closeup of the bottom area, and the dent is clearly under the Y of Penny.

The ACSC lists a variety of styles, with a caveat that this occurred, "... on a vertical strip of six stamps ... These appeared only in a late 1934 printing, and was quickly repaired."
The problem is that my dent does not match any of the varieties listed in ACSC. Here is a copy of the entire cover (Sorry, nothing on the back):

I wonder if some of our CDS experts can pull the date from this example? I did a tight scan, and some color manipulation, and the best I can guess is that this is a 1932 date, which puts it too soon for the variety. Any advise on the actual date? Thanks.
