1851-57 12c Washington

Txstamp, here are the guide dots I was able to get from that block of 28. I included the line of the stamp to the right to show spacing as well. Since 9 rows have guide dots, the guide dot chart will be 9x10. The chart will look awesome.

Moyock13, can you get me a link to that block of 9?

jaxom, try this.

Here are a couple more margin copies.

40L1


71R1 - this one could have gone two ways save for the left margin. It could have been 73R1 just judging by the guide dot placement. But since it has a large left margin...

Moyock, that block of 12 is 61-63L1 --- 71-73L1 --- 81-83L1.

Here are the guide dots that I got from the block of 9.

Jaxom, Nice! Do we need to find another 83L1?

Thinking out loud ... showing the absence of something can be just as important as showing its presence. While collecting data, it would seem valuable to have the corners of all positions imaged even if some may not show a guide dot, they may coincidentally show some other feature unusual to a particular position. Just my two cents.

jaxom, here's another block of 4. Looks like 45L1 46L1 / 55L1 56L1.

John, you make an interesting point, as usual.
My first take is that the way Rick is doing it is fine, since this guide dot cross-reference is really just for when you see a guide dot, and want to know what position it corresponds to.

If you are starting from scratch, and want to plate the stamp and don't have an obvious guide dot, then you don't necessarily always go to this chart, you go to a separate plating chart, like the one already in Neinken, with drawings for "all" the positions, including those with no guide dot.

This should be viewed as a helper to the existing plating diagrams.

That said, having pictures of all of the positions in addition to drawings is a separate issue -- pictures/scans of real stamps are great, and stamp smarter already has the infrastructure to support that model --- which Rick has well utilized for 1c and other stamps.

Moyock, I will need another 83L1 but I put in what I had. I grabbed those other two images. Thanks.

John, the top row has upper right guide dots that I show. I also show the lower left guide dots for column 1, column 10 has no guide dot (except 10L/R), and the bottom row has no guide dot. I will squeeze 10L/R in like I do on the 3c charts. I feel that showing the corner would not be helpful in those cases where there is no guide dot. They would all look the same. I am finding that those without a guide dot are harder to plate.

Chipshot, your stamp is harder to plate without a guide dot, but I think your stamp is 80L1.

I am hoping to make a plating program similar to what we are making for the 1c to plate the 12c. It is just theoretical at this time. I am working on questions to ask but have a basic starter plan shown here:

Moyock, that block of 4 was a nice find, Thanks.

I do not know if anyone has noticed, but have been using the 1847 10c Washington database for my 1851 Washington images, just using two image slots that I can remove later.
Here is what I am currently working on for the left pane.
The guide dot chart and spacing chart are about 40% done.


Here is a problem. Neinken says the spacing between the first and second columns "even to slightly higher". To me, column two looks slightly lower. This came from the last block of 9 posted. Sides are straight.

What about this stamp?
The stamp to the left and right is higher.
This puts it in column 4 left, 6 right or 8 right.
I came up with 18R1.

Here is another one. It is a column 10 stamp. The stamp to the left has no LR guide dot. That makes it a bottom row stamp. It is lower than the stamp at left, so it is left pane. Position is 100L1.

Here is a strip of 4. The right stamp has no guide dot, therefore, column 10. The 10th column stamp is lower than the one before, therefore, left pane. The mark in the "E" of "POSTAGE" is unique that led to 68L1. So the strip is 67-70L1. It gives me a couple more guide dots and three spacing chart images. However, I prefer the spacing images to show the whole intersection.
