Hi Jimmie, a very well done and informative artical on Quackenbush and his inventions, although a lot of this as been done in the past by John Atkins in the Airgunner mag.
But you have done a excellent job in putting it alltogether in one artical which is easy to find and read. keep up the good work, and l look forward to see what you come up with next.
ATB,
Mick.
