You can get approximate prices off Gunbroker. What year was it made? Thre is a year code on the barrel flats.

You still haven't said if it's PG or stratight stock; splinter or beavertail.

I will probably get flamed by the usual flamers but in my opinion beavertail, gold triggers and pistol grip reduce the value.

Many of these Spanish guns are very nice and far better than the new comparably-priced guns.
