In the Scott Catalogue, go to Republic of China, then to the Back of the Book section, past the Postage Dues, Past the Military Stamps, and you will find a section for Taiwan (Formosa). It is Scott #10.
I just discovered this app called Stamp Identifier. I just now tried it out on the above stamp and it worked flawlessly. I don't know if it was created bu Colnect, but the search results use Colnect data. Check it out. Available in the iPhone app store. I don't know about Android.
I uploaded the stamp image shown at the top, and the possible matches show up below it (this image shows only half the screen.)
It is also available in the Google Play Store for Android. I discovered it a couple of weeks ago, when I was trying to identify some recent Japan used singles. It didn't find every one I was looking for, but it was sure a time-saver. (And I'm not sure, but I think it *is* produced by Colnect.)
