We often watch several of the antique shows that are on cable on just
the chance that a slide rule may show up from time to time. Well,
today was the jackpot. "Collectible Treasures" on HGTV (home and
garden tv) had one that featured scientific instruments for part of
it. The shows a Thatcher Calculator and a Fuller Calculator. The
price they gave for the Thatcher was $3500, and for the Fuller $1000.
It was nice to see the two they had and perhaps someday...
