Doesn't fire at all? I'd get a couple of dummy rounds and pull the stock and see what's wrong. Either the safety is not working, it isn't cocking the hammers/strikers or someone has sprayed cheap lube in the action and it has turned into varnish. The last was quite common when WD-40 first came out. I have made some money on that stuff cleaning sxs that got it sprayed in the trigger openings. I left my sewing machine home for a number of years and my mom lubed it it has taken years of good lube to free it.
