Early GB Cancel Question

[Deleted]

I am not very familiar with GB Victorian/KGV-period cancels.  I'm hoping someone more knowledgeable can help me with this.

A sample of what has me stumped:


I have some extra time on my hands and am trying to keep mentally busy.  I decided to go through a long-neglected set of Victoria stamps and catalogue plate numbers and ID postmarks.  I do not have a reference book for the PMs but found this website which is helpful:

The Great Britain Philatelic Society

I seem to be unable to ID where these postmarks are from.  They appear to me to be part of duplex cancels (ref. 3rd from left), but I'm not sure.  Am I correct in my guess that these are from London, or at least another major city with multiple post offices? Any help with location along with the significance of the numbers and letters would be much appreciated.

@flygare I have a question for you. Where do you get the plate numbers? I know on the imperfs that the number is in the scroll on the side but I don't find them on the perforated stamps?

They're also in the scrollwork. There are a couple types of Vic Penny Reds. The earlier version has a maltese cross in the upper corners (Scott #3)instead of the position letters (Scott #33). I do not know as fact if #3s have the numbers, but I am inclined to think that they do not.

Thank you for your answer. I will look again at my stamps.

Flygare, the oval obliterators are London District cancellations. The first one has a "W" at the top for the West district and the second has "SW" for South West district. "N" is for the North District and "NW" for the North West District. I believe that the numbers below the District designation identifies the particular post office where the letter was received. The "LS" cancellation is a Special London Obliterator. "LS" stands for Lombard Street.

Flygare, take a look at the following link that has old books that you can download. This particular link has old British postmarks (1840 to 1876): archive.org/details/cu31924030133536
You can view the book online or download it as a PDF document.
