all ten points of which would make them a type II
Several points & questions:
1. Where are you getting the "ten points"? It's not from Scott. As I noted in another of your threads, you would benefit greatly by obtaining a copy of the Scott US Specialized catalog. A used copy a few years old can be had very reasonable.
2. Your illustrations are confusing. You show two stamps, then reverse their positions for showing the reverse side, then show close-ups of only one of them. It would be more clear to deal with one stamp at a time. They can both be in the same thread, however separating them into two consecutive posts would provide clarity.
3. All that said, yes, I agree that you appear to have Type-II coil for the one you show enlarge images. As for the watermark, the single-line USPS watermark often shows just a small piece of a single letter and can be very tricky to see. The odds are far greater that you have a Scott 454 rather than a 491, as Nicholas suggests. Additionally, Paul Schmid's "The Expert's Book" on the Washington Franklin issue notes on page 127 "The watermark on Sc.# 454 can often be very weak and thus difficult to detect."
4. Since Type-II comes only in vertical or horizontal coils, it cannot be trimmed from any sheet stock. The very slight curvature to the cutting of the perforations is also consistent with the knife of a coil affixing machine.
Add:
It s also important to know exactly what to look for. Here is a (poor) image of a strip of Scott 455, the Type-III cousin, showing a single line watermark, note with the direction of the web of the paper for rotary coils, that that individual letters are on their sides, rather than upright.

Here is an outline of the strip of 5 drawn onto the general layout image of the sigle-line watermark, taken from Schmid's book. Note that a small portion of a letter is all that appears on some stamps.
