Some of the Marlins did have the rear band over the barrel stamping. When they changed the band placement there were barrels still in stock with the stamping for the previous model and they were used. I have a '46 model 36 with this condition. I would like to see a pic of the action as well, and it may help solve the mystery. I was thinking all the old barrels were used prior to 1950 but stranger things have happened I guess.
Looking forward to a pic of the action,
Rick
