I also grabbed the the Burlington Bulletin #10 tonight to coincide with the studio review.
Just a note.. I can't believe I missed this.. DOH! The louvered air filter door for the main air reservoir that was located behind the cab bulkhead; this door immediately behind the cab doors is not a screen as depicted on the GGD E7 but on CB&Q E7's a shuttered door. The delivery state in 1945 was a shuttered door later changed to a smooth sheet metal door and in some cased completely removed in later years.
disposition:
CB&Q #9921-A
Built November/1945, C/N 2948, Later numbered BN 9921 (3/2/70), Traded for a SD45 9/3/70
-Maintenance Grab Irons added 1950-1955 no data is given as to exact date.
-Never received stainless panels.
The photo comparison above clearly shows the louvered air filter door. I think I can change this door, I will see what I can do.
This is "nit-picking" guys... I am just following through with the prototype versus the model thing..
