Details of the Morton curing process, years of production affected, etc. to be found in Ned Schwing's The Browning Superposed, John Browning's Final Legacy. Briefly, production affected comes from roughly six years in the late sixties, early seventies, high quality stock blanks (crotch black walnut) more likely to be cured by this method due to low availability at time, guns so stocked more likely to show damage (or not show it on the exterior). Other Browning firearms (including rifles) of the period also affected. Many restocked by Browning under warranty, a service obviously no longer offered. If you consider buying such a gun or rifle and no damage is apparent action shoulders or barrels near forend, best to request removal of forend and stock. Market value for such guns depressed by reputation without regard to individual condition.
