Is this scott #461 on a postcard sent to Norway, thanks

Nice card!

I didn't have time to confirm Type I, so I'll assume your ID of Type I is correct.

I don't see the watermark on the sachet -- or at least it is not obvious to me, anyway. Can you roughly draw where you see the Wmk190?

If no watermark, then it is Scott US#499(Mar1917) which does come primarily in rose color in addition to other minor color shades. That issue date is significantly closer to the postmark date of 30Jun1919, than the issue date of US#461(17Jun1915).

Best wishes that it is Type I with Wmk190!

OK, for some reason I completely missed the last picture in your original post where you marked in green. I'm getting too old for my own good!

(Please see a few posts down for the layout of Wmk190.) The letters USPS in Wmk190 are arranged in a diagonal fashion (or tall X arrangement), so there are no letters directly above/below, although you might partial letters at opposite left/right edges on a horizontal. If there is more than one partial letter present, both partial letters must be on a diagonal or horizontal, but not a vertical. Therefore, of the 3 possible watermark letters you marked, one or more of them are artifacts of the of the MB detector. process and the fact that the stamp is still on card.

If indeed you have 1 or 2 partial letters in the corners, I would think the expertizer would invariably have to lift the stamp to verify in order to provide a written certificate. When they see something small in the corner, they will write that they cannot confirm it is unwatermarked. It typically has to be a sufficiently large part so they can confirm it is a specific part of one of the letters for them to say it is Wmk190. Else, they might give a neutral or no opinion.

Best wishes!

For those who don't collect US, this is Scott Wmk 190 (single-lined USPS)

KHJ , thank you for the good answers :-) and I completely agree with you, the 3 points cannot be visible at the same time in that position, I have noticed that. As you say, the watermark's misalignment/location/how can i read it etc. is in this, as in other cases, quite frustrating.
I fear many people put away potentially good stamps/varieties because they are left with good indicators but none worthy of decision due to high value.

But I must clarify this for sure, find better tools. But then I guess Morley Bright is one of the few options you have, without removing the brand. I actually have 4 cards found, from the same area, are stamped from 1915-1919, same stamp issue, basically, all T1, all perf 11, all measure 19*22 so 99% sure Plate.

With Morlay, I've found "good tracks" on 3 out of 4. Oops, now I probably appear like an over-positive dreamer who has lost his head and gets sidetracked by all opposition that says otherwise :-)

I'm just good at keeping all possibilities open :-) But I made the post because I want opinions, input, counter-arguments that are forgotten/suppressed, so shoot :-)

does it happen that some sheets have several watermarks applied in sometimes different directions etc.? Think I remember reading it once. And a lot of strange things happened in the production back then, which today makes this exciting.

The reason I ask is because, in this stamp that I have 3 clear "areas", I took a different photo, changed the light, etc., then I see a paper impression of a clear and complete letter S in the middle of the center of the stamp. I will upload those pictures soon

I’m not seeing any watermark.

I have ordered vm fluid..a few weeks ago, takes time

The S that appears is quite distinctive and the size appears correctly. I should probably send the card in for examination.

You agree that IF :-) this is 461, then it is a good object, since it is on a card sent in 1919? I guess that's unusual

I found this USPhila site here that gives prices realised at auction for Scott 461. If you scroll down, you'll find one a similar postcard with a flag machine cancel. This cancel is said to be commonly found on the 461. However, that card is dated 1916.
