12 gauge Remington double barrel shotgun model 139157 can you give me any info age value etc?

Sounds like it's probably an 1894 (hammerless), they only made them until 1910 and around 42,000 starting at serial 100,000 so that's near the end. The value is greatly dependent on condition, condition, and condition. Best to search gunbroker.com, gunsamerica.com for a like condition for sale (or sold) for value.
