Now I got this part from Surplus Shed in Pennsylvania, a great place to look for oddities, specifically optical stuff, but they have a ton of other things, like this. Anyway, the last time I ordered a few of these the package had the original U.S. Navy inventory tag. Check out what Uncle Sam paid for this.
Yup, you read that right, $16,818.00! Now I would say that makes Angus here just a little more valuable, wouldn't you? Nothing but the best for the Robotorium.
