This is one of the first parts I designed for the old Shapeways shop. It is mildy updated -- the filter drain cock is now included. And of course it is no longer made of FUD, with its problematic support-side textured surface, but in much higher resolution 8K resin.
See the late Des Delatorre's WNW Albatros D.V build on the
https://aircraftmodels.com for placement. (Of course he scratched his own from brass tubing and such).
