The Franchi and the Aya are in nice conditions. The old Sauer & Sohn Model Habicht (proofed in November 1930, and itself at the bottom rung of Sauer products even back when new), alas overall is NOT, leave alone mentioning the visible coarse ministrations of the village blacksmith with a welder; and indeed, as much as I can recall, that one may have came from a stock of more or less dilapidated guns somewhere from the Near East, that Sarco had imported in bunch and barrel, lumped together.
I know what it would be worth here (little, if anything), but cannot say about the USA.
