Hi everyone. I am hoping that someone on the forum can help me with an old air pistol left to me by my grandfather. I have tried to do a little research on it and have found some information but really need to get some idea of its value with a view to selling it. It is the silver version wth the letters MGR just above the trigger, and there is no trigger guard just the trigger, and it is in good working order. It lacks the cocking tool to pull the plunger down from the base of the handle, but I have had one made. The pellet is then loaded into the barrel in the same manner as the gat pistols. Photos could be sent to an email address. Thanks as any information would be great.
