Re: 63 Stamp pad
I think you can see the grain on the deck surface that was under the head. You can also see it continue slightly into the cleaned up area of the exposed pad, but the outermost part of the pad is too pitted and then scrubbed to retain the grain. A lot of blocks including most big blocks have pretty smooth grain to begin with.- Top

Re: 63 Stamp pad
If you hold an LED flashlight near the edge and shine it across the surface, what little grain that remains may show up...Mike

Re: 63 Stamp pad
Your first picture you posted was the clearest. I can see them, they are faint but they are there. The surface near the edge of the block is as someone described, too pittted from corrosion so they are gone in that area. I would use some navel jelly to coat that area of the pad. You may have to do this a few time to get it good a clean. Wipe it off and then take some brake cleaner and spray the area which will clean any residual navel jelly out of the depressions which make it cleaner and very dry without any lint deposit left from a rag or paper towel. Then take more pictures using lower light and an LED flash light shined across or parallel to the stamp pad surface to light up the pad when taking the pictures. A higher resolution camera would also help.
