Byzantine Wars with Islam in Syria & Palestine - A Heraclius Countermark

In my quest for cheap ancient countermarks, I recently landed a pitted follis of Maurice Tiberius with what looked like a countermark - the seller correctly identified the host coin, but missed the countermark. In hand, I was (I think) able to attribute it, a monogram of Heraclius' name in a circle. It was apparently issued by Heraclius during his Syrian wars with the Muslim Arabs, and was used in Palestine.

The most helpful information was from a "sold" listing on FORVM - I quote from this listing:

"Heraclian countermarks on Byzantine copper coins in seventh-century Syria" by Wolfgang Schulze, Ingrid Schulze and Wolfgang Leimenstoll discusses finds near Caesarea Maritima, where this example was found, and concludes, "During the military conflict between the Byzantine Empire and the Muslim Arabs in Syria in the years 633-36 Byzantine coins were countermarked by the Byzantine military with a Heraclius monogram. Countermarking most probably was exercised predominantly in Palestine I and was carried out to revalue the few circulating copper coins in order to remedy the general supply gap and disastrous shortage of cash."

This is the FORVM coin in the listing - the countermark is beautiful:

The FORVM example has a much clearer countermark than my example. The host coin on mine, despite some pitting problems, is remarkably intact in terms of identifying characteristics - the oddly under-sized reverse compared to the full-size obverse is interesting. The countermark, unfortunately, is not very clearly struck - my "enhanced" version show why I am attributing the way I am. Any corrections (or disagreements) welcome, as always. I was staring pretty hard to attribute this and I might be seeing things.

Are there any others of these out there? This Palestine countermark seems to be scarcer than the Sicilian issues of Heraclius, but I think these were all issued in abundance.
