The "T" marking typically refers to an item for which postage is due. Here's an excerpt from a Linn's Stamp News article that may or may not refer to your example:
Quote:
From October to December 1919, Belgian post offices ran out of postage due stamps. As a substitute they applied locally a large black "T" handstamp to postage stamps of the 1915 series. Because the handstamps were applied locally, these stamps are not listed by Scott. However, authentic uses of them on cover are quite valuable.
Here's a link to the entire Linn's article for your review:
