Feltwad,
I can't post them but now have some pictures of the Richards double. If you send me an email I will forward them to you. It appears to be a Belgian proofed barrel with the typical E over LG in an oval. There are also a number of other markings on the barrel; 169, 3IH, LJM, JA1 and what look like superposed 3's. I suspect some of these are inspector marks. There are a few others that are not legible.
