Why? If you only want "stock," your options are very limited. In fact, it seems fairly unrealistic. I don't believe I've ever seen more than one or two new lugged steel frames for sale on the floor (more likely in the window or high up on the wall) of a bike shop. Just because a model is featured on a maker's website as a standard doesn't mean you can just go to your local dealer and pick one up, or get it in your size any quicker or much cheaper than you can get made-to-measure in the color of your choice.
I'd seriously recommend considering the latter - it's not as big a deal as some imagine. Casati have an interesting lugged steel model: Casati Campionissimo Page. There are a few dealers. Maybe someone somewhere has one in stock, but if you don't want to do a LOT of digging, or consider the possibility of getting it shipped from overseas, you'll have to just take what you can get and forget about what brand or model anyone might suggest. You're really better off just ordering one from the factory. But if you want Italian, you better hurry and place your order, so you don't have to tack an extra month (August shut-down) on your wait time.
