So they made almost 8 million NM barrels, or barrels period, and this just happens to be a NM barrel?
Back on topic, no, I've never come across any old frankenguns. I made one. Does absolutely destroying a perfectly good Series 70 NM Gold Cup count? I bought one of those crappy 13 +1 frame conversions from Para-Ord when they first came out. I let the original frame go too fast. It was horrible. I hang my head in shame.
