Ro11B Possible Dbl Or Twisted Transfer

I am not very knowledgeable with transfer variety's. Does anyone see a twisted or double transfer here. DT is listed for this stamp. It could also be something entirely different too. Seems most noticeable at left and right sides and in the word "cents" at right.

Also the word "three" at left and the "I" of internal at right. This is a "twisted transfer" version of a double transfer. A lovely item and as a collector of double transfers I am very jealous.

Notice that the left side is double left and below, and the right side is doubled to the right and above. That was the direction of this particular twist.

Thank you for the verification. I did notice the the I of internal on second look, but missed the "three". Too bad it is not in better condition. Is a twisted transfer less common than a double transfer??

in this case it is the double transfer. Double Transfers generally happen in one of three ways.
1) The siderographer makes a mistake in the positioning, but the extra lines do not get burnished out completely when they fix the mistake. These are usually the large double transfers, like on the 2 cent bank check and certificate.
2) the transfer roll twists during the rocking in process of entering the position and extra lines show up. This is what happened here.
3) The transfer roll slips during the rocking in process and creates extra lines that way. These will sometimes show up as extra frame lines, and sometimes in the lettering. It might show up in one direction or both, but without any twist.
Many of type 2 and 3 occurred during plate re-entries (but could have been from the original entry), but type 1 happened when the plate was first created.
The foreign entries on the 60 cent second and third issue and the $1.50 second issue were caused by the transfer roll going too far during the entry of the positions above and adding lines of another value design; the transfer roll had more than one design on it (they usually did). Either no one noticed or no one cared about those few lines when the lower positions were entered.

I have a large list of books regarding revenue stamps to get. I was hoping for a recommendation for a complete writing regarding types and variations to include private die. I have the "Boston Book", Aldrich Census, and a couple other basic books. What say you for the next best one to purchase.

Thank you all for the comments. Revcollector, would it be proper to identify this as a twisted double transfer, or does it follow just a DT, and a twisted transfer is a different type of impression.

It's a double transfer. If you want to identify it as a twisted transfer, that works but since that phrase is not used in the catalog, fewer will understand it right away. If you want books to help with revenue plate varieties then the Shift Hunter Letters and the APS Revenue Unit Columns book are essential.

I have heard the term twisted transfer somewhere, so thought it to differ from DBL transfer. As long as they are the same, its all good. Thanks for the book advice, both those are on the list, but now at the top.

EDIT: Meant to ask about revenue canx listings, Tolman???
Disregard, found what I was looking for.
