Can anyone point me to (or provide) some information on Arrieta Crown Sabels?

The particular one I am looking at is a 20 bore 27" with markings from Hansen & Hansen, Southport, CT on it. Serial number on it puts it around 1983. Hand detachable locks, engraving only on boarder, screws, and 2 crowns. Nice piece of wood, leather pad, Gunmark pigskin case.

Where would these fall in the Arrieta lineup? The bottom, close to the bottom, middle?

Thanks!
