1851-1861 3c Washington Compression Charts

Here is the guide dot chart for the right pane of plate 4. I had to scale it 50% to fit here. If anyone has a copy of one of the three positions showing the left guide dot, I would appreciate a copy to fill in the holes. Comments appreciated.

Great work, jaxom. Thanks!

Here are the compression charts for the right pane of plate 4. The B relief chart is compressed at 90% and the full pane chart is compressed at 65% as needed to post here. There were 10 incorrect Lund images from the 3 cent plating website for this pane. 200 images complete, only 2400 more to go. Comments appreciated.

I looked at plates 6, 7 and 8 in our database. We do not have enough images to complete charts. In fact, we do not have the images for most of the plates. What a shame. Not sure what I will do. Make partial charts?

Here is the guide dot chart for the left pane of plate 3. I had to scale it 45% to fit here. If anyone has a copy of one of the five positions showing the left guide dot, I would appreciate a copy to fill in the holes. Comments appreciated.

I want to thank you for all of your work. I have not started plating any stamps so have nothing to add at this time but appreciate your attention to this project. It truly is a great thing. I hope that you continue the efforts and bring more collectors into helping you. Best wishes.

A new compression database is now implemented and has been added as a 'tab' to the existing 3C page on Stamp Smarter as shown below

Note, if you do not see the new tab, please force your browser to fetch the updated page with a 'refresh' (typically the F5 key).

Rick is doing a great job on this significant effort. If anyone can assist in anyway (i.e. source plated images), please let Rick or myself know.

Here are the compression charts for the right pane of plate 3. The B relief chart is compressed at 85% and the full pane chart is compressed at 60% as needed to post here. There is only one C relief stamps on this pane so I left the image with the relief B chart. 400 images complete, only 2200 more to go. Comments appreciated. I can complete 1 chart in a week if I spend 10 hours per day working on it and I have the images to work with. That still puts completion date at early next year. But real work will get in the way.

In case anyone is interested, here is the guide dot chart for the left pane of plate 1 late. I had to scale it 48% to fit here. If anyone has a copy of one of the four positions showing the left guide dot, I would appreciate a copy to fill in the holes. The second image shows the dot location indicating the revision number by the number of dots. This will show you if you have the latest revision on one of my guide dot charts. Comments appreciated.

Here are the compression charts for the left pane of plate 1 Late.

Don has gotten the 3c guide dot charts implemented into the 3c database, accessed as a new tab. These guide dot charts are full size as created. Please check it out.
