A closer overhead view shows some of the unique plumbing topside, this detail also varies with each version and we have accurately modeled the differences. Note the uniform boiler bands which are all individually soldered in place. It is a common practice by other builders to use individually applied bands only where there is a boiler seam that needs to be hidden, all of the other bands are photo-etched on the boiler sheeting before it's formed. This practices accounts for the lack of uniform appearance you often see with other models.
