It is amazing to me how long it sometimes takes me to think of the obvious.
When you unpack the Star stuff that you have just bought it would be interesting to know if you find any of their prototype machines. From the ones I've seen pictures of they would look pretty much like a basic star but altered in some pretty obvious ways. If you do find any, I hope you'll post pictures.
Also I can not help to wonder if you will find any of the straightlines. I think that they made about 20. Three are known, maybe four. Again pictures would be nice.
And Star also made a bench mounted bullet casting machine with, I think, 100 cavities. I'd love to know how that worked and I hope you find one of them as well.
