As time passes, more and more of these old classics are being refurbished and refinished. It is becoming common practice to clean-up bores and/or replace choke by honing bores. That coupled with work on exterior of barrels to prep for re-blue can lead to very thin barrels made of weaker steels that are candidates for failure. Many can not recognize a refinished gun or do not have tools to measure barrel thickness.
