Good evening

Needing some help with the cancel on this stamp. I'm told it's either 1) a double cancel, or 2) a fake cancel.

If it's a fake cancel, I can't understand why that would be since it greatly diminished the value of the stamp. If it was canceled twice, can anybody speculate how that might have occurred?
FYI - Just to keep the thread from derailing, I've confirmed that the stamp and overprint are authentic.
Thanks for any thoughts! You folks always seem to have great information!
Dear Polimon,
Your stamp is perf. 13 ½ and, as far as I know what is published in specialized literature, there are no originals of 240 réis, Madeira surcharge, with this perforation.
So, at first sight, it is a reprint. Probably it is a 1905 perf. 13 ½ reprint (and not 1885 perf. 13 ½) according to the yellowish colour of the paper we can see on screen and also because of the shape/contour of the horizontal low teeth.
In this case the cancellations will be fake or apocryphal.
