Types of paper and their first use [according to Pettigiani] and their relative scarceness:

It would have been logical to deal with the 10c Rivadavia here and now, but as you may have guessed this is quite a complicated value of which both Bardi and Pettigiani hadn't understood much.....

So I prefer to postpone the discussion on the 10c until the very end of my dealing with the separate face values hoping that in the meantime someone else might shine his light on them as well.....

SF 1 November 1945 "c" for both
SF 3 March 1945 "R"for Pettigiani

The MI 3 stamp was considered by Bardi as dubious, Pettigiani refers to the existence of just 1 [one] copy. One may wonder how we can be sure that it is not RR1 ??? With just one copy it is hard to establish the vertical inter-row distance of 30mm OR [!] 35mm.

Anyone having a scan?
