Help With Papal States Stamps: 80c Block Of 4, Mezzo Bajocco, And 2 Bajocchi Pair

Hello everyone,
I need some help with a few Papal States stamps. I know that authenticating these issues is notoriously complex, so I would really appreciate your opinions on the following three items (scans of both front and back attached):
1. 80 Centesimi perforated block of 4: Is this a known reprint or a recognized forgery?
2. Mezzo Bajocco (rose/pink): Does this one look genuine to you, or is it a reprint/forgery?
3. 2 Bajocchi pair: Does this pair look genuine? Also, what are your thoughts on the gum on the back? To me, it looks completely regummed.
Thank you very much in advance for your time and help!

The first stamp ,the block of 4 was made in 1889 by M.J.B. Moens . It should have 11 1/2 perforations and comes in both pink and rose pink . That reprint has a shiny surface but should have a glazed surface .One of the attributes of a Moens reprint is the frame lines which show nicely on your copy is Vertical lines are continuous: horizontal lines interrupted .

Thank you for your assessment. However, I am a little puzzled by two points in your comments, and I wonder if you could take another look at the photographs.

First, you mention a perforation of 11.5, whereas I measure approximately 13, or slightly above, on my block.

Second, regarding the dividing lines, I understand you to say that the vertical lines are continuous and the horizontal lines are interrupted. However, looking at my block, I see exactly the opposite: the horizontal lines appear continuous, while the vertical lines are interrupted.

Perhaps I am misunderstanding your observations, but could you please double-check these two details on the photographs?

I would appreciate your clarification. Thank you for your help.
