Thanks for the info. Any age bracket on this gun? I removed the barrels in the conventional manner; removed forestock and broke open but they didn't immediately come off. It did come off later while I was handling it but I don't know what I did to accomplish this. Now, The only way I can get the barrels back on and closed is to remove a small pin (less than 1/8"dia.) from the barrel assembly. Once together, I can't reinsert the pin. It is supposed to go into a forked link in the receiver. I don't know what purpose the link serves but simply breaking the action does not allow me to access the hole for the pin and get it back into the link. Any hints?
