More On R152 Varieties - Recuts Or Double Transfers?

Sorry - having to experiment to increase file size to maximum allowable. Click image to enlarge.

Opinion
No,
There a 5 lines, counting up from the lower frame, till it meets the vertical shaded area under "2"

In your assumed added line, this is just a lighter impression, perhaps from plate wear.

I've yet to see anything that impresses me as a "double transfer" on
any of these, possibly wishful thinking.
"Re cuts" maybe.

I get these often in random auction lots, I was not aware there is a silk paper, how do I identify those please?

rod, you probably know granite papers with embedded threads of various size and fineness. US silk paper is similar but the threads are spread out in the paper matrix so that there might be only one or two in a stamp. So you'll have to check both sides of stamp. Use something like "US revenue stamp silk paper" it as a search term and you should be able to find images that show a/the thread(s) prominently.

Of course, tiny threads can always get stuck on the back of stamp. Plus there are a lot of people that mistake stamps with brown or black specks of paper impurities as being silk paper.

Aha!
Thanks HB ! Yes I recognise granite well, should be easy to
find threads, as you describe.

hy-brazil-you are confusing different kinds of revenue silk papers. It is true that EXPERIMENTAL SILK has only a few threads, often only one or two. But the regular silk papers of the second, third, fourth and fifth issues (up to this 1875 era two cent), and the proprietary issues of the same era have many obvious threads.

Edit: I see your other thread with additional photos. I am reviewing that and may change what is written below. 2nd Edit: Bold text below has been added after reviewing a complete transfer in your other thread.

Can you post the pair photo again but with the ability to enlarge it as you did with photos in your other thread? This may lead to seeing other DT elements hidden or implied by the size of the current photo.

I see something different on the joined pair, locals4me. You are correct the two images were not entered into the plate at the same horizontal position with entry being higher in relation to the other. With just two entries, while the right one seems high, one cannot determine which is properly placed and which is not. That said, what I see on the right image is a short transfer at the bottom based solely on the pair shown. The curved heavy element at the extreme corners was impressed into the plate, but not as deep as normal while the visible bottom horizontal line was not properly impressed and thus is broken and lacks the same dimension and quantity of ink as it should have had. With seeing a complete transfer in your other thread, I can now see this as a DT. As I have no ready comparison at hand and the photos you provided are too small for me to see I cannot state if one more horizontal line, below the broken one is missing. I can see that is not the case.

A short transfer occurs when the sideographer does not impress the full transfer roll image on to the printing plate, either at top, bottom or both. The width of the design, as measured across the transfer roll is normally fully impressed, unless the transfer roll or plate area has been damaged.

The sideographer "trying again" can result in a double or triple transfer. Not trying again but cutting in the design elements by hand results in a recut even though the plate has not yet gone to press thus not suffering wear.
