@CAPPilot posted:Bob mentioned the K4 1120 by Williams. A lot of folks do not know about this Pennsy engine and the three others that were streamlined. Most know about the K4 "Torpedo", which is much different looking. In fact, I like the looks of the streamlined engines better than the Torpedo. Here is Williams #1120.
love this ,took me years to get one,,,just wish it had a whistle,,but stunning
