Need Some Help With This 1851 Cancel

MM,
As soon as you said, "one pass" I then agreed with your suggestion.
I am only a US pretender, I know nothing of the production of their stamps, but using the British Rose engine as an example, I think the scroll work was produced vertically on a face plate in a Rose Engine lathe.
"Slightly out of register" makes perfect sense to me, this is very fine work.

Takes nothing away from the stamp, makes it more interesting.
The lathe work between the rosettes is just beautiful, beats the framework of the Penny Black in my opinion.

I have at least one Troy cancel from 1851, it is blue. I might even have more than one style. Also in my collection are part India stamps used in MA (Boston), NJ, CT, OH, and even a few yet to be figured out. Several are on cover...

I don't think Boxborough is going to be a winner but I just found a Foxboro cancel from 1857-61 on ebay that looks promising. I won't be convinced totally until I see a good example on a cover from closer to 1851.

Here is one of my Troy, NY covers from 1851.

Lots of "boro's" in MA. Northboro, Lanesboro.......

One can eliminate Attleboro ... it was still being spelled "borough" until around WWI.

Attleborough, Mass was officially changed to Attleboro on Aug 9, 1894 as published in the Postal Bulletin of 8/27/1894. Part of the mass changings of -borough to -boro and other name standardizations of PMG Wanamaker. Granted, some individuals and businesses may have continued to use the old spelling for some time afterwards.

Truro by any chance?

So, I have found a potential match. It isn't perfect for a couple reasons but seems pretty compelling in other ways. What does everybody think? I am pretty sure this new cover has a Foxborough CDS.

I just dug out the stamp. I guess it probably isn't going to work, the mystery cancel has larger, wider spaced letters in the town name.

Winston, in your post here -

you indicate that this 'Troy' is 1851, which I assume is a typo.
If that is a 1E stamp, then its probably 1852.

LOL, I grabbed the wrong image I guess. I have previously used that image as proof that stamps were not always used up as quickly as is usually assumed.

The first time I posted that image, nearly ten years ago now, I was told it wasn't an OB stamp because it was used too late!

That's a good example of an out of period use. Nice cancel too.

One of the odd facts about the part India/thin paper stamps, particularly the 3c stamps, is they were all used much later than the other early printings from Plate 1E. Speculate is all we can do to explain why.
