Scott 247 National Memorial Ottawa Stamp

Posting this oddity on Scott 247....Looked at my sheet Plate 2-1 and saw this irregularity on Position 40. Hoping I can get help verifying whether this oddity is a fluke or a possible constant variety.
It is not on my sheet 1-2.

Any help appreciated

Robert, I do not see a difference ?

Peter

Peter..There is no difference, same pic, one circled and one not

Robert

Ottawa war memorial. Looks like a spent casing. Will have to go through mine now.

Oh, my bad. You are talking about that small line that looks like an engraver's slip ?


Peter

Not bad at all Peter, and yes..May be a slip.

Robert

I thought that there was only one engraving done for each design of stamps and this was then reproduced. In that case an engravers slip would show on all the copies in the sheet. It also does not look like a repair so perhaps some accidental marking ?

I agree with the above. If one wants to point out an unusual stamp oddity, it would be helpful if it was shown with a normal example for comparison. AND an illustration of a full stamp to give an idea of what stamp this is all about.

I also agree with anthraquinone's thinking, the engraver makes the die, the platemaker makes the plate - two completely different skill sets and equipment.

I don't have your oddity but I have one of my own. I have two black lines running through the date 1939. One is quite prominent, the other which just grazes the tops of the numbers is less so.

I don't have a second copy to compare it to, so I hope my face will not be red on finding out that's the way they all are.

Ok, now can we get on with other collectors checking their stock to see if it is a possible constant variety.
Any help appreciated..Thanks ahead of time.

Hi itma..Those lines are normal for sheet plate 2-1..I have made an Excel sheet on what I call reverse plating and which stamp goes where associated with their position..Still processing the finished product.
Robert

itma..Here is a small example of what I am working on...

Thanks, Robert. So my face will only be half red.

Frank.

Frank...No problem my friend..Stamping is an on going learning lesson.
I still depend on guys like John Becker to keep me on the right path...I am always learning.

Just curious, what is a spent casing ?

Lines through 1939:



The lines in the date area are simply a matter of the registration between the two colors. When the black is printed low, the steps print into the frame area. Compare the 2 stamps above. It seems logical to me that this could occur with any combination of frame and vignette plates.

I have no idea what "reverse plating" is.

Hi John...Just a nick name that I apply to a full sheet, taking each individual stamp in each position so some one with just one stamp could put a position of his/her stamp..Not earth shattering, trying something different..i know, a waste of time..correct..?
