Wow! You are all being great: This information is of paramount interest to me, I'm fascinated by the variations - thank you all for being specific as to the details.
I have interest in building based on this guy's plans:

(perhaps you have seen these plans, perhaps the creator is even a Dakka' member)
They seem to closely resemble the old
FW version, but of course they are radically different from the
WD#132 plans, so for me it's a toss up between the old-style
WD plans (which would be a smaller tank) or the newer plans available from the link above (a larger tank and most likely more in proportion with the commonly available kits).
