third stamp is a fiscal revenue stamp
the second stamp is a fiscal / revenue postage due
taking a guess that the 1st stamp is a telegraph stamp
All three are Austrian general revenues.
I agree with Nigel - all 3 are revenues from Austria.
Thanks all for the review and determination.

Hi jmh67, Thanks very much for posting this link. This look very useful indeed. It's great to have a reference at last which shows all the 1870 designs.

Hi Don, The images in jmh67's link complement the Forbin listing well. However, on its own, Forbin's listing of the 1870 set is not all that helpful for identifying these stamps with confidence.
