Alex....very nicely detailed cars. The flush window "problem" is something that an individual will have to decide whether or not it is bothersome. The Daylight has always been one of my favorites and I have it well represented on my Twin Lakes Central railroad. Along with the steam locomotive, I have all of the K-Line 21" cars. The steamer is the GS-4 that MTH produced and just so you know, the colors do not match perfectly. Williams produced a nice ribbed set of scale streamliners back in the late 80's or early 90's that match the locomotive perfectly as I also have all six of those cars. As a matter of fact, I have a 7 car 20" set of cars that Weaver produced and they match almost perfectly with the locomotive. In addition, I have the Alco PA ABA set and a set of ABA F-3 units. I love the Daylight scheme!!
Congrats on your new set Alex!
