If the picture is attached properly, I would like any information regarding the two pistols shown. The lower pistol will take a SW 38 bullet but I don't know the actual caliber. The only marking except for Iver Johnson Arms on the barrel is the number 7801 on the trigger guard. The upper pistol is a smaller caliber, maybe a 25 cal, with same barrel marking and the number 68528 on the trigger guard. Any info would be appreciated. Thank you.
