No doubt it's a 578, the 5-pins and the engraving pattern identify it. The Model 803 is similarly engraved, albeit a bit more detailed, is a 7-pin action, but has an assisted opening feature as standard. 5-pin Arrietas utiilized a coil spring for the intercepting sears, whereas the 7-pin Arrietas utilized a leaf spring. Coil vs. leaf -- one is generally not being thought of as better than the other, but rather they are different methods of doing the same thing.
Your Arrieta 578 was optioned to be 28ga. smallbore (a 10% add on premium over a large bore) and to have a rounded action (another 10% premium over the std. square action). Articulated front triggers are standard with all Arrietas, sideclips could be spec'd to any Arrieta at N/C. All Arrietas were hand-built and custom-made.
Yours a a beauty!
