Finally finished the WS 72xx, couple of small details to add once stripped down, coupling and connecting rod oil pots and 3D printed balance weights.
There isn't much of the original kit left in the upper works to be honest, some of it is replacement parts in a thinner gauge and some of it to convert to a first batch engine. To be fair there comes a point where it's easier/faster to do all of it yourself rather than modify the existing bits in the kit to suit your new parts.
For the record the original etched parts are cab front, valances & steps, smokebox and boiler wrappers. The chassis was pretty much out of the box with a few extra details and modifications here and there.
I opted for a 3D chimney, I know it's the right shape and size and it needed no fettling, the joys of 3D prints when they go right.
I tend to be over cautious fixing printed parts and like a battleship approach to securing them, usually with a secondary mechanical fixing, in the case of the chimney I printed a formed plug that fits inside the wrapper, the spigot is raised just above the outer wrapper which locates into a corresponding pocket in the chimney base. To make doubly sure 0.8 mm rivets were then added through all the parts, they also acted as detail parts for the chimney fixing.
