Thanks to David Lajer of Aires, and to IPMS/USA for giving me the opportunity to review this sweet little detail! I recommend it highly.
These pitot tubes are cast in pale tannish gray resin, with three tubes protected by casting sprue on three sides. This arrangement will provide the modeler with enough nose tubes for three planes, or in my case, enough for one plane and two mistakes. The shipping package is reseal-able, so you can keep the extra tubes secured.
There is little to say about these elegant little tubes, after all they are pretty small. But I micrometered them and they are well with scale tolerances. There is a little bit of variability in the length of the real thing anyway, so this is a minor consideration. More importantly, having this small detail greatly enhances a very prominent place on the model.
