It looks like a mechanically solid K-frame 22 with a rough finish.
I'm no expert. But I've seen K-22s in rough shape for about $600.
That would be about right in western Washington.
Is the Spanish writing on the side of the frame normal? That one threw me for a loop but I am too lazy to dig one out to compare.
"Marcas Registradas" is the Spanish equivalent of "Registered Trademark." It's normal.
