They've certainly been well-maintaned. Still, I'd have to have a real fixation on that particular historical issue to dump that kind of money.
Sinking money into guns as an investment is a bad strategy. For example, these two guns took 78 years to accrue their current value. That's 78 years I have to sit on them, keeping them maintained and secure.
On the other hand, I could have put some money in the stock market at the same time, and I'd be much better off.
Sometimes it’s nice not to destroy the world for a change.
