You're welcome, Xavier... and thank you, in turn, for sharing your work with us.
You might already be aware of them, but if not, I'd like to offer the suggestion that you check out the guys over at Model Junkyard--- they do beautiful work, all scratchbuilt, and have been working on some of the very same subjects lately... Subscription to their newsletter gets you access to some of their e-books of techniques, and exclusive downloads from time to time (free roadsigns just today; I just got them). One of their documents I have covers how they went about a scratchbuilt gas pump in styrene. I wouldn't say any of it was make-or-break in importance, but it's informative, and they really do achieve a nice result.
