Raimey,
First of all thanks for the information and taking the time to research those related threads. This gun I think is most similar to the gun in the first thread that you posted (#422242). Rifle shell holder is on top of the stock though, rather than the bottom, which seems a little more practical to me. The letters "SCH" appear on the barrel selector, which also activates a rear sight. What does the "SCH" stand for?
