Perhaps you should look at it a different way. There were some very good tools made in the past and the makers may have had hundreds of different tools to offer. Todays makers have a fairly limited selection.
Another way of looking at things is that just because something is old doesn't mean it should be set aside. Some older tools do take more time to put back into service than others, many do not require a lot of work.
Sure a new LN #3 would look and in some ways work better than either of my Stanley/Bailey #3s. The wood or the end product wouldn't show any difference. My two #3s were less than a third of the price of the new #3 and only required a little work to put into great working order (one actually came pretty much ready to go).
