Sam - Hope I do not spoil your day, but the CB&Q 4-8-4 you have numbered 5612 is out of sequence. The vestibule cab Burlington 4-8-4's began at #5621 thru 5635. The oil-burning, vestibule-cabbed O5b's were numbered 5626/27/29/32 (converted to oil in 1950-51). Also, your vestibule cab does not equate with the prototype. The Burlington's vestibule cabs were pretty much (if not exactly) like those employed on the Great Northern, or your Milw S3 4-8-4. The chaffing plate butted up tightly with the back of the cab and the compression pistons were much shorter then what you have portrayed. And there was no canvas covering employed. Perhaps this Otto Perry photo might prove helpful:

I convey this information not in the spirit of "gosh, aren't I the smartest guy in the room", but, rather, recognizing your absolute adherence to the prototype which your models exhibit, I believe you would want to know. Please do not take offense ! Your work is outstanding !
