Something's missing. It's the trigger! NRA Museums special projects coordinator Ernie Lyles shows John Popp that Winchester replaced the trigger on the model 99 with a thumb trigger. They were made from 1904 to 1923 for young shooters. The idea was it would pull less, making the shot more accurate for a beginner. They weren't a big hit. They made 76,000, but most went to Australia. See it and thousands of other wonderful firearms at the NRA National Firearms Museum in Fairfax, Virginia.
