Wanted: giant demonstration slide rule

[EebamXela]

I'm in the market for a large slide rule for my collection. If you know of an available one please let me know.

For those equations that are too big for smaller, less gigantic slide rules to solve, get MEGASLIDE. Guaranteed to work, because it's too big to fail!

With a 10 foot scale, you can get 4 digit precision instead of 3. In fact, my Otis King has a 10 foot scale.

(Except mine's a K model and the picture is an L model. The L model had a log scale, as well.)
