Bonny,
As Ted stated, there are fewer parts in a Darne than in what Darne refers to as a "Tipping Gun". Go to the forums section of doublegunshop.com . The second heading,
Double Gun FAQs shows "Darne compilation...." Page 5 of the pdf is a small pamphlet by Darne. It depicts a chart (in green background) at the bottom comparing the Darne's action versus a "tipping" gun. Depicted in the chart are the parts utilized by both the Darne and "tipping" gun in 4 categories. The Darne utilizes 25 parts compared to the tipping gun's 41 utilized in fastening, percussion, ejection and safety. Gil
