For those who have studied barrels attributed to having been made by Parker Bros. please take a look at Gunbroker lot No. 194624408 and give us your opinions. The "PB" in the shield on the underside of the left barrel can't mean anything but "Parker Bros." unless I am mistaken. If I recall correctly the serial number is in about the correct range?
