Alco RS2/3 stack question

RS-2's and early RS-3's came with air cooled turbos with the stack off center and lengthwise to the car body.   When they were replaced with water cooled turbos the stock was mounted on the center line and cross wise to the car body. 

As far as I know they did have screening over the top of the stack in both arrangements.

Thank you Stuart. That will help alot. This stack is rectangular. Would the inside follow the outline of the outside as if it was a simple sheet metal structure or was there a round or oval pipe inside the rectangular box? I ask because some of the models without smoke seem to have simulated oval opening at the top. In some pics it seems there is a lip extending slightly beyond the lip of the rectangular top. Would this lip be the screen frame covering the whole stack?

post script, after looking at more prototype pics I appears I have a wide latitude on how to make the screen. They all look a little different.

The early 1950's Alco-GE factory stack for the RS2, RS3, RSD4, and RSD5 had an oval opening with a screen.

However, many roads modified them to plain rectangles without any visible screen.

Thanks Tom, I have a Weaver RS3 that has simulated oval screen I will copy for now. My first attempt is made of styrene with an oval hole milled in it. I may make another using brass sheet and a rectangular screen.

Here's some shots of the 8223 on the Adirondack.

Thanks Mario, 8223 came up a lot on my searches. That must be a later water cooled version with the center stack. The K-Line has the off center stack.

I am waiting on some screen material to finish mine. Stay tuned.
