Santiago, noted your water column pictured at about 230 on your tape. In consideration of your meticulous attention to detail, you might want to give thought to obtaining a "Poage Style H water column with wheel", from American Scale Models. They were used extensively across the Burlington. The one depicted looks like a style I have never seen either in person, or in photos, on the Q. The ASM column is a bit pricey ($125), but a nicely executed model. Just a thought.
