Ok, got the paint off, here are pics of the full pad, plus the close up of each, plus the cowl tag. I knocked a chip of paint off the cowl tag when trying to clean it, hence the silver patch at the lower right corner. Very interested in your thoughts.
Thanks for the example, looks like we both are in a similar situation, although you have both stamps the same, and I've got one right and one wrong. Its nice to know this happened often, and there are examples of this to support each other's case.
Whoops, had to split the post, the pics were too big, see 2nd post below also...
