Yes sir, we have come to the same conclusion. I'd add that I'm of the opinion that the relatively small size of MU, and its limited output, are also factors.

Looking purely at serial numbers (always risky with Spanish shotguns), it appears MU made about 12,500 guns during the period 1951 - 1968. That's an average of about 725 guns a year, all price points.
